Now it does not reach Spitsbergen, but turns towards Greenland, which contributes to more warm weather on the American continent, but “freezes” northern Siberia, writes NewsOboz.org with reference to Russian Jew.
The first to report the stop of the Gulf Stream doctor dr Gianluigi Zangari, a theoretical physicist at the Frascati Institute in Italy, in a journal article June 12, 2010. The article is based on satellite data from the Colorado Aerodynamic Research Center, coordinated with the US Navy's National Oceanic and Atmospheric Administration. The author pointed out the stopping of the rotation of water flows in the Gulf of Mexico and the breaking of the Gulf Stream into parts. Subsequently, the images were changed on the server of the Colorado Aerodynamic Research Center and now it is difficult to say by whom and when.
How was the current going before?
The cold and denser Labrador Current “dived” under the warmer and more dense mild course The Gulf Stream, without preventing it from heating Europe, reaches Murmansk. Then the Labrador Current “surfaced” off the coast of Spain under the name of the cold Canary Current, crossed the Atlantic, reached Caribbean Sea, heated up and, passing through a loop in the Gulf of Mexico, already under the name Gulf Stream, freely rushed back to the North.
The Gulf Stream was part of the thermohaline circulation system, key element thermal regulation of the planet. It separated England and Ireland from becoming a glacier. Smoothed out the climate in the Scandinavian countries.
After Dr. Zangari's message, the Canadian Parliament created a commission to find out the real state of affairs with the Gulf Stream near the coast of the state. It was headed by the well-known US oceanologist Ronald Rabbit, a technologist for processing biomass of the World Ocean and improving environment. A special dye that does not harm the flora and fauna of the ocean was poured into containers that exploded at a certain depth and, thus, the flow of movement of water masses was tracked. The Gulf Stream was not discovered as an existing current.
But, as it turned out, the self-regulating system called the Earth “worked” this time too. According to research, the current “crept” 800 miles (1,481 kilometers) east of the zone former Gulf Stream. According to satellite images, the temperature of this current has increased relative to the Gulf Stream. This means that the evaporation rate in the warm zone above the ocean has increased.
A small digression: most people believe that moist air is heavier than dry air, but this is not true. Molecules of oxygen O2, carbon dioxide CO2 and nitrogen N2 are heavier than water molecules H2O.
What does this change mean for us?
Presumably, a very cold winter of up to -45 degrees and little snow in the European part of Russia, Western Europe will be covered with snow, and hurricane winds will rage on the border of the fronts. In mid-February 2011, instead of frost, spring came in Canada with a temperature of +10. America, apparently, will also not be left without a “carrot”. This is confirmed by the recent cold weather in Montana, South Dakota, Texas, Arkansas and Tennessee.
The Gulf Stream is a system of warm currents in the north. parts of the Atlantic Ocean, extending over 10 thousand km from the Florida Peninsula to the Spitsbergen Islands and New Earth. Discovered by Spanish sailors at the beginning of the 16th century. and it was called the Florida Current. The name Gulf Stream was proposed in 1722 by B. Franklin. Originates in the south.
part of the Florida Strait. as a result of a strong surge of water into the Gulf of Mexico by trade winds. through the Yucatan Strait. When entering the ocean, the power of the current is 2160 km per day, which is 20 times greater than the flow of all rivers on the globe.
Coming out into the ocean, it connects with the Antilles Current and at 38° N. latitude. its power more than triples. Further, G. moves at a speed of 6-10 km/h in the north along the Atlantic coast of the North. America to Bol. Newfoundland Bank, beyond which it is called the North Atlantic Current.
The width of the stream from South to North increases from 75 to 200 km, the thickness is 700-800 m, and the water temperature on the surface decreases from 24-28 to 10-20 °C. G. has a huge impact on the nature of the north. part of the Atlantic Ocean and the adjacent part.
North the Arctic Ocean, as well as the climate of Europe, creating very mild climatic conditions in temperate and arctic latitudes.

The main branch of this current originates in the Gulf of Mexico (where its name comes from, meaning translated from in English"Gulf Current") and enters the Atlantic through the Strait of Florida; then the current is diverted north by the Great Bahama Bank, an underwater platform located southeast of the Florida Peninsula.
Coming out of the Gulf of Mexico, the Gulf Stream carries large clusters floating algae of the genus Sargassum and different types thermophilic fish (including flying ones).
Off the east coast of Florida, the boundaries of the Gulf Stream are clear, especially the western one. The sparkling blue of this current contrasts sharply with the greenish-gray colder waters North Atlantic.
The flow itself is not just a homogeneous mass of a moving ribbon of water. It consists of several streams having approximately the same direction. At its eastern edge there are numerous rightward curling eddies; some of them are even completely separated from the main stream.
Near the Grand Bahama Bank, the Gulf Stream receives a branch of the North Trade Wind Current and follows generally parallel to the east coast of the United States, but at a short distance from it.
It is with the warm waters of this current that the mild winter on the Bermuda Islands is associated. Near Cape Hatteras (the coast of North Carolina), the Gulf Stream turns northeast and heads towards the Great Bank of Newfoundland. Here it meets the cold Labrador Current and also comes into contact with colder air coming from the north.
As a result, the area experiences almost constant fog. From the Great Bank of Newfoundland, the Gulf Stream moves eastward to the shores of Europe (this part is called the current Western Winds). Approximately in the middle of the North Atlantic, the Gulf Stream divides into two currents. One of them follows further east to the shores of Europe, and then, turning south, forms the Canary Current, the other, called the North Atlantic Current, gradually deviates to the left and continues to move to the northeast.
This current passes off the western coast of the British Isles, where a branch is again separated from it, heading west to the southern coast of Iceland - the Irminger Current. Another part of the North Atlantic Current, the Norwegian Current, follows the coast of Norway.
Ideas about fathering, still popular in our time, took shape in the last century.
The Gulf Stream was compared to a river changing its position (meandering) in the ocean. The research that existed at that time in this part of the ocean made it possible to classify the current as geostrophic (i.e., formed by the balance of only two forces: the pressure gradient on the water and the Coriolis force) currents. On the surface of the ocean, the Gulf Stream has a width of 70-100 km, and the depth from the surface is about 500 m.
The current passes along the hydrofront - the interface between cold (and less saline) slope water in the west and north and warm (and more saline) water Sargasso Sea in the east and south, and the Gulf Stream jet itself meanders within a distance of about 500 km (Fig. 2, 3) - along the hydrofront region, leading to the formation of warm (to the left of the jet) and cold (to the right of it) vortices with a speed of up to 1.5 m /with a diameter of up to 400 km.
This information about the dynamics of the Gulf Stream waters was obtained mainly by analyzing data on water temperature and salinity, i.e. thermohaline parameters.
However, within the framework of existing ideas about the nature of the Gulf Stream, it is impossible to explain why, outside the flow, masses of water (its bed) move in reverse side why the current pulsates, stops, and then picks up speed again, and after 10-20 days the situation repeats.
And why have numerous attempts to reproduce these properties on a model failed? We tried to answer some of these questions using data from direct measurements of current speeds.
Not long ago, a new device appeared in the hands of oceanographers. This is a drifter - a float with an antenna that allows you to monitor the movement of water, and from here determine the speed and direction of the current, in this case at a horizon of 15 m.
Information about the drifter's position in the ocean is transmitted via satellite to the Data Collection Center. More than 400 drifters have been launched in and around the Gulf Stream over the past 10 years, each providing information for an average of one and a half years. As a result, a huge amount of material was collected about currents and water temperatures, on the basis of which we conducted our own analysis of the dynamics of the Gulf Stream and tried to understand its nature.
An area of the ocean is identified in which the speed is much greater.
Current speeds here decrease from south to north, from 1 to 0.5 m/s. In the southern part, the Gulf Stream is about 100 km wide, and in the northern part it is more than 300 km wide. From the more detailed information presented in Fig. 5, 6, it follows that the Gulf Stream currents are quite stable in direction, at least in its main part, south of 38°N.
Let us now consider the behavior of currents in the Gulf Stream.
To do this, let us analyze the route typical for the Gulf Stream and the course of the current velocity module (Fig. 7, below).
It can be stated that within the Gulf Stream, especially its southern part, drifters, and therefore masses of water, move predominantly unidirectionally and along isobaths, or more precisely along the shelf edge. In this case, the water flow does not move strictly along the isobaths, but makes slight fluctuations to the right and left in relation to the movement of the main water flow.
Such fluctuations are small in the part of the Gulf Stream south of 38°N. and are significant to the north of it. With such a predominantly unidirectional movement of the water flow, the speed pulsates, reaching values close to zero at minimum. Sometimes the water flow moves in the opposite direction, although weakly. What reason and force makes the waters behave this way: stop, and then pick up speed and stop again, etc., i.e. pulsate in time and space?
This behavior of currents clearly contradicts the concept of them as thermohaline and geostrophic.
It seems that a powerful stream of water flows into the ocean from the Gulf of Mexico through the Strait of Florida in the form of a jet, which forms the Gulf Stream. Previously, this was exactly what was believed. This is where the current got its name: the Gulf Stream, which translated from English means the river of the Gulf (of Mexico) or the stream of the Gulf.
However, this impression is deceptive. Later it was found that the Gulf Stream is mainly formed by the mentioned cold slope waters from the north and the warm waters of the Sargasso Sea from the south, but not by the Gulf of Mexico, from where practically no water comes. It also turned out that in the middle part of the Gulf Stream the water flow is much greater than in the southern part, in the Strait of Florida (and these facts are in no way consistent with the thermohaline and geostrophic nature of the current).
It is no coincidence that they began to talk about the Gulf Stream not as a river flowing out of the bay, but as a current carrying its waters from the Florida Peninsula.
The Gulf Stream is a large sea current in the Atlantic Ocean.
Thanks to its warm waters European states, located on the shores of the ocean, have a milder climate than without it.
It would seem that what does water and air have to do with it, and how is the influence of the Gulf Stream on Europe so great?
The answer is very simple: the warm waters of the current heat the air, which with the wind reaches the coast of Eurasia, preventing the countries located on the continent from freezing.
The power of the current is truly impressive.
The water flow per second is more than in all the rivers on the planet and amounts to 50 million cubic meters. m. There is as much heat in the Gulf Stream as would be produced by 1 million nuclear power plants.
The Gulf Stream receives its supply of warm water from the Gulf of Mexico and carries it along the coast North America almost to Canada, where it turns into open ocean, heading towards Europe.
Wasting a colossal supply of heat along the way, the current still brings so much energy to the mainland that tundra has not formed in Europe. And it should, because... above 60 degrees northern latitude live in other places on the planet reindeer, and in Europe at the same latitude there are green meadows.
The biological productivity of the Gulf Stream has not been the subject of special research. The biomass of plankton in the Gulf Stream zone is also small. The Gulf Stream region cannot be a feeding area for either boreal or subtropical fish, since the former avoid the warm waters of the Gulf Stream, while the latter find favorable conditions near frontal zones Gulf Stream and Atlantic waters.
The importance of the Gulf Stream is its participation in the “breeding” of the largest commercial species of fish and zooplankton.
When faced with cold waters in the north of the ocean, the current creates so-called “banks”, which are an ideal habitat for flora and fauna. Fishing thrives in such places commercial fish: herring, cod, etc. The development of small crustaceans forms “feeding fields” for many cetaceans that organize annual migrations here.
The Gulf Stream is a powerful warm Atlantic current. The influence of the Gulf Stream is noticeable even in the Arctic Ocean in the form of the North Cape and Norwegian Currents. The Gulf Stream is the culprit of the unstable weather conditions in this district.
Gulf Stream
GOLF STREAM, a warm current in the mid-latitudes of the North Atlantic Ocean, moving in a northeasterly direction. The most fast current in the Atlantic, the Gulf Stream is one of the very powerful forces nature.
The Gulf Stream's water consumption is about 50 million cubic meters water every second, which is 20 times more than the flow of all the world's rivers combined. Locally, in each individual region, the direction and nature of the current are also determined by the outline of the continents, temperature conditions, salinity distribution and other factors.
The Gulf Stream in a broad sense is the entire system of warm currents in the North Atlantic, the core and main driving force of which is the Gulf Stream
It is known that north of Cape Hatteras the Gulf Stream is losing stability. It exhibits quasi-periodic fluctuations with a period of 1.5-2 years, similar to fluctuations in the jet stream in the atmosphere, known as the index cycle. Considering the influence of the Gulf Stream on the climate, it is assumed that in the short-term historical perspective a climate catastrophe associated with disruption of the flow is possible.
In particular, according to Doctor of Geographical Sciences, oceanologist A.L. Bondarenko, “the mode of operation of the Gulf Stream will not change.”
This is argued by the fact that no actual water transfer occurs, that is, the flow is a Rossby wave. It carries heated water masses from the Indian Ocean and the south Atlantic to the northwestern coast of Europe.
But the North Atlantic Gulf Stream can't explain all the disappearances
Thanks to the Gulf Stream, European countries adjacent to the Atlantic Ocean have a milder climate compared to regions lying at the same latitude.
Over the North Atlantic westerly winds take away heat from masses of warm water and are transferred to Europe.
This current is directed in a narrow stream along the coast of North America. An additional factor of deviation in the eastern direction is the Coriolis force. The continuation of the Gulf Stream to the northeast of the Great Newfoundland Bank is the North Atlantic Current.
Now the Gulf Stream for Europe and the USA is a generous gift of nature to their economies and populations. Kitchen weather northern hemisphere located in the North Atlantic and Arctic Ocean. The Gulf Stream acts as a heating system in it; it is also called the “stove of Europe”.
The cold and denser Labrador Current “dives” under the warm and lighter Gulf Stream without preventing it from warming Europe.
The density of the Labrador Current waters is only 0.1% higher than the density of the Gulf Stream waters. As a result, the Barents Sea does not freeze all year round, and in Europe palm trees grow and houses with cardboard walls are built.
If suddenly the Labrador Current becomes equal in density to the Gulf Stream, it will rise closer to the surface of the ocean and block its movement to the north. That's it, we've arrived. We get a pattern of currents ice age.
Studies of ice in Greenland show that climate change processes could occur within three to ten years.
Over the next few years, air temperatures in Europe will be equal to those in Siberia. Now giant oil spills have been discovered in the waters of the Gulf of Mexico. Oil has been leaking for months from a well drilled by BP on the bottom of the Gulf of Mexico.
The Norwegian Current disappeared along with it. The first to report the stoppage of the Gulf Stream in August 2010 was Dr. Zangari, a theoretical physicist from Italy. The average water temperature in the north of the Gulf Stream dropped by 10 degrees.
The Gulf Stream is a warm current in the Gulf of Mexico that bends around Florida and flows along the east coast of the United States to approximately 37 degrees north latitude. and then breaks away from the coast to the east
Letters are coming to the editor asking for clarification on whether the warm current will really disappear soon.
Similar currents exist in the Pacific Ocean - Kuroshio, and in the Southern Hemisphere.
For the same reason, the Northern Hemisphere as a whole is slightly warmer than the Southern. The primary reason for the unusual nature of the North Atlantic is that slightly more water evaporates over the Atlantic than falls as precipitation.
In place of the water that has sank into the depths of the North Atlantic, water comes from the south, this is the North Atlantic Current. Thus, the causes of the North Atlantic Current are global, and are unlikely to be significantly affected by such a local event as an oil spill in the Gulf of Mexico.
But even this magnitude of seasonal anomalies is quite common and is observed in one region or another almost every year. Reports that the Gulf Stream between the 76th and 47th meridians in 2010 became colder by 10 degrees Celsius are also not confirmed. But the ice continued to melt, and at some point, water from the lake began to flow into the North Atlantic, desalinizing it and thereby preventing the sinking of the water and the North Atlantic Current.
A continuation of the Gulf Stream is the North Atlantic Current, carrying a cooled stream in the north to the Southern Hemisphere.
Changes in the continuity of the Gulf Stream are a topic of debate in scientific circles. Several factors are involved in the origin and direction of the Gulf Stream. Almost a third is in the path of the Gulf Stream. The first refers to the Gulf Stream itself - an ocean current along the eastern coast of North America up to 90 kilometers wide and with a speed of up to several meters per second.
Individual currents in the oceans are combined into systems included in the basin-wide circulation. The most famous sea current is the Gulf Stream. This name is translated into Russian as Current from the Gulf. It has been preserved since those distant times when it is believed that the current arises as a stream of water rushing from the Gulf of Mexico through the Strait of Florida into the Atlantic.
It is now known that only a small fraction of the Gulf Stream waters are carried out of the Gulf. The current coming out from there is now preferred to be called the Florida Current. Ocean flow reaching the latitude of Cape Hatteras at Atlantic coast USA, receives a powerful influx from the Sargasso Sea.
This is where the Gulf Stream itself begins, a mighty “river in the ocean”, going to a depth of 700 - 800 m and reaching a width of 110 - 120 km. Another feature of the Gulf Stream was noted: upon exiting the ocean, it deviates not to the right, as it should be in the Northern Hemisphere under the influence of the Earth’s rotation, but to the left!
This is the result higher level ocean in its subtropical part. The average temperature of the surface layers of the current is 25 - 26° (at depths of about 400 m - only 10 - 12°). However, in the Gulf Stream, at a distance along the length of the ship's hull, there are large temperature differences, reaching 10°, and changes in color and transparency sea water happens literally before our eyes.
In the surface layer of the current, a core of high-temperature waters, most pronounced at the very surface of the ocean, and a core of high-salinity waters centered at depths of 100 - 200 m are usually found.
This feature can be traced back to the Great Bank of Newfoundland. Thus, the idea of the Gulf Stream as a very warm current passing through colder waters is valid only for the surface layer, but even in it the warmest waters are only a few degrees higher than the surface temperature of the waters of the Sargasso Sea.
Surface velocities of the Gulf Stream itself can reach 2.0 - 2.6 m/s.
Even at depths of about 2 km they are still significant: 10 - 20 cm/s.
Gulf Stream Current
When leaving the Strait of Florida, the flow power is 25 million m3/s (and this value is more than 20 times the flow of all the rivers on the planet); after the addition of the Antilles Current (from the Sargasso Sea), the power of the flow increases to 106 million m/s.
And such a mighty stream rushes northeast to the Great Bank of Newfoundland. From here, the Gulf Stream, like the Slope Current separating from it, turns south, joining the North Atlantic gyre.
And across the ocean, to the east, towards Europe, the North Atlantic Current rushes, which is sometimes considered part of the secondary oceanic water cycle.
Gulf Stream Wikipedia

GOLF STREAM (English - Gulf Stream, literally - gulf current), one of the most powerful warm currents of the World Ocean. Located in the North Atlantic Ocean; flowing from the Strait of Florida, it heads along the coast of North America to Cape Hatteras, where it breaks away from the coast. Next, the Gulf Stream spreads in the open ocean approximately along 38° north latitude to 40-50° west longitude. In this area (sometimes called the Gulf Stream Delta), the current divides into several branches, the main of which, called the North Atlantic Current, extends northeast to the coast of northern Europe.
Sometimes the entire system of warm currents from the shores of the Florida Peninsula to the Spitsbergen Islands and the Novaya Zemlya archipelago is mistakenly called the Gulf Stream.
The reasons for the formation of the Gulf Stream are the meridional distribution of wind, the water density gradient, and the rotation of the Earth.
When entering the ocean from the Strait of Florida, the transport of water by the Gulf Stream is 25-29 million m3/s, which is tens of times greater than the flow of all rivers on the globe. In the ocean, water transport by the Gulf Stream increases and at 38° north latitude reaches 80-90 million m3/s. When leaving the Strait of Florida, the width of the Gulf Stream is 60-75 km, the speed of water movement is 1-3 m/s.
After the Gulf Stream separates from the coast in the area of Cape Hatteras, the width of the Gulf Stream increases to 100-150 km, and the speed decreases to 0.5-1.5 m/s. The Gulf Stream covers the upper layer of the ocean with a thickness of 700 m to 1 km. The most important feature of the Gulf Stream as a jet stream off the western coast is its instability associated with hydrodynamic reasons.
An image of the Gulf Stream from space does not show a continuous flow comparable to a river in the ocean, but rather a wide band of complex eddy-like movements with a general direction of movement to the northeast, the so-called Gulf Stream meanders and eddies, ranging in size from several tens to several hundred kilometers.
The Gulf Stream carries a large supply of heat and salts. Average annual temperature water on the surface when leaving the Strait of Florida is over 25°C with a salinity of 36.2-36.4‰. As the current moves to the northeast, the temperature of the surface layer in the Gulf Stream delta region decreases due to interaction with the atmosphere to 13-15°C.

In general, the Gulf Stream and its continuation in the form of the North Atlantic Current have big influence on the hydrological and biological characteristics of the seas and the Arctic Ocean itself, as well as on the climate of European countries.
Masses of warm water heat the air passing over them, which is carried by westerly winds to Europe. Important climate phenomenon is the North Atlantic Oscillation, the occurrence of atmospheric circulation anomalies (including the formation of cyclones). The shift in the position of the Gulf Stream and changes in its flow and temperature determine the dynamics of global ocean circulation.
Although these fluctuations are not very large (tens of kilometers, 1-2°C and no more than 5-10 million m3/s), they are the most important climatic factor northern part of the Atlantic. It is currently impossible to reliably determine whether the North Atlantic Oscillation is the cause of these changes or whether the oscillation itself is to some extent a consequence of them.
Observed interannual changes in the position and intensity of the Gulf Stream significantly change the transport of moisture from the Atlantic to Europe, especially in winter.

JAPANESE TREND, OR CUROSIVE
Blue Current - is formed from the North Equatorial Current of the Pacific Ocean, which, turning to N due to the meeting with the Philippine Islands, approaches the island of Formosa and, starting from here, is called the Japan Current. This current has a width of only about 100 nautical miles, then it deviates to the right and goes west of the Liu Kiuz Islands to the Japanese Islands.
The eastern edge of the current is less defined than the western one. The speed of the Japan Current is initially about 35-40 nautical miles, and near the Liu Kiuz Islands it reaches 70-80 nautical miles.
In the summer of the northern hemisphere, the speed of the Japan Current is greater, sometimes reaching even 100 nautical miles. The water temperature of the Japan Current at its beginning in August is about 28°. Approaching Japan, the current passes through the Van Diemen's Strait between the island of Nipon and the Liu Kiuz Islands, widens and reaches a width of 300 nautical miles, and its speed decreases.
On the northern shores of Nipon, between the latter and the Japan Current, which has moved to the right into the ocean, a cold current appears - Oya-Sio, coming from Kuril ridge islands; its temperature is several degrees lower than Japan. Having passed parallel to the northern tip of Nipon, Ya. T. gradually loses its strength, deviates to the right into the open ocean and, starting from here, is called western drift Japanese current.
It goes east across the ocean between parallels 40-50° N. w. at a speed of 10-20 nautical miles. Approaching America, the current divides, part of it turns N along the coast of Canada and Alaska, forming a warm Aleutian Current . The speed of this current is insignificant. Another part of Ya. T.'s drift turns south and goes under the name California Current along the coast of America.
The average speed of the California Current is 15 nautical miles. Having paralleled the southern tip of the California Peninsula (tropical), the current gradually deviates to the SW and W and joins the North Equatorial Current.
The Japan Current is similar to the Gulf Stream in many respects. Japanese current drift golf stream
Warm Gulf Stream is a current in the Atlantic Ocean that begins near the Bahamas and ends its path near Europe and becomes the North Atlantic Current. Gulf Stream - amazing phenomenon. Firstly, it is warm, and secondly, the Gulf Stream warms eastern Europe with its waters. It creates a warm climate in Eastern Europe: it is thanks to him that they grow here deciduous forests and even palm trees, but the tundra does not stretch out.
Why does the Gulf Stream exist?
The thing is that the hot and cold waters of the Atlantic Ocean form a kind of conveyor belt.
golf stream current on the world map
Hot equatorial waters rise to the top and form a current, and when they reach the end of the path, they cool.
At the same time, they sink down into the water column and move back to the beginning of the flow. Thus, warm Gulf Stream and exists.
Some scientists say that the Gulf Stream is slowing down its waters, and some say that it has stopped completely. It's hard to figure out who's right right now, but the Gulf Stream does have several reasons to slow down.
The first one is global warming.
Glaciers are melting rapidly, diluting their fresh water salty oceanic. A decrease in salinity disrupts the balance of the Gulf Stream. The second reason is the very large amount of oil that was spilled in the Gulf of Mexico. This also affects it, disrupting and slowing it down.
Stopping the warm Gulf Stream carries many dangers: cooling of Europe, climate disruptions, and the emergence of an ice age.
It plays a huge role in the life of our planet.

GOLFSTREAM, (English Gulf Stream, literally - gulf current), a warm current in the North Atlantic. IN in a broad sense G. is a powerful system of warm currents that extends 10,000 km from the coast of the Florida Peninsula to the islands of Spitsbergen and Novaya Zemlya. The Gulf proper begins in the southern part of the Strait of Florida as the drainage current of the Gulf of Mexico at its confluence with the waters of the Antilles Current and continues to the Great Newfoundland Bank. The reason for its origin is the large surge of water by trade winds through the Yucatan Strait into the Gulf of Mexico and the resulting significant difference in levels between the Gulf of Mexico and the adjacent part of the Atlantic Ocean. When entering the ocean, the power of the current is 25 million m³/sec. (2160 km³ per day), which is 20 times the flow of all rivers on the globe. In the ocean, it connects with the Antilles Current, and the power of the G. increases by 38° N. w. Reaches 82 million m³/sec. One of the features of hydrodynamics is that, in violation of the general pattern of movement in the Northern Hemisphere, this current, upon exiting the ocean, deviates not to the right under the influence of the force of the Earth’s rotation, but to the left. In the ocean, G. moves in a northerly direction, along the edge of the continental shallows of North America, and at Cape Hatteras it deviates to the northeast, towards the Newfoundland Bank. After passing it, at approximately 40° W. etc., the Atlantic Ocean itself turns into the North Atlantic Current, which, under the influence of western and southwestern winds, crosses the ocean from east to west, gradually changing direction off the coast of Europe to the northeast. When approaching the port of Thomson, a branch separates from the North Atlantic Current - the warm Irminger Current, which partially enters the Greenland Sea, skirting Iceland from the west, but the main mass moves to the west, skirts Greenland from the south and follows along its western coast called the West Coast. Greenland Current in the Baffin Sea. The main flow of the North Atlantic Current continues into the Norwegian Sea and follows north along the western coast of the Scandinavian Peninsula under the name of the Norwegian Current. At the northern tip of the Scandinavian Peninsula, a branch separates from it - the North Cape Current, which follows east along the southern part Barents Sea. The main flow of the Norwegian Current continues to the north and, under the name of the Spitsbergen Current, passes along the western shores of Spitsbergen. North of Spitsbergen, this current plunges to depths and can be traced in the Arctic Ocean under cold and desalinated surface waters as a warm and salty intermediate current. Width G. on different areas sea 75–200 km, flow thickness - 700–800 m, speed - 80–300 cm/sec., surface water temperature from 10 to 28°C. The system of warm currents in Greece has a great influence on the hydrological and biological characteristics both the seas and the Arctic Ocean itself and the climate of European countries adjacent to the Atlantic Ocean. Masses of warm water heat the air passing over them, which is carried by westerly winds to Europe (in the west of Norway at the latitude of Magadan they grow southern trees). One of the branches of the Gulf Stream - the North Cape Current - reaches the Kola Peninsula, allowing the Kola Bay and the waters of the sea ports on Murman, in particular, not to freeze (the air temperature in Murmansk deviates from the average values at this latitude to 11ºС).
In Russia, F. F. Yarzhinsky announced the passage of hydrocarbons along the Murmansk coast for the first time after studies of the temperature regime of the Barents Sea at a meeting of the Russian Geographical Society in 1870 (previously there was a hypothesis of the German geographer A. Petermann). Subsequent observations by Academician A.F. Middendorf confirmed his data, although in the capital they were of the opinion that “there is no and cannot be any Golfström.” N. M. Knipovich with the staff of the Murmansk scientific and fishing expedition (1898–1908) discovered 4 branches of the North Cape warm current in the Barents Sea. Southern, Murmanskaya, ran parallel to the coast Kola Peninsula, then dividing into two streams (towards Novaya Zemlya and the Kaninsky shallow water). The expedition established a connection between the migration of juveniles of bottom species and their accumulation on shallows and banks with the warm currents of the river, and it was proposed to expand the fishing area. New opportunities in the study of geology opened up in the middle of the 20th century. with the advent of more advanced scientific equipment.

The Gulf Stream is a powerful warm Atlantic current. The influence of the Gulf Stream is noticeable even in the Arctic Ocean in the form of the North Cape and Norwegian Currents. The Gulf Stream is responsible for unstable weather conditions in this area. GOLF STREAM, a warm current in the mid-latitudes of the North Atlantic Ocean, moving in a northeasterly direction. The fastest current in the Atlantic, the Gulf Stream is one of the very powerful forces of nature.
The water flow of the Gulf Stream is about 50 million cubic meters of water every second, which is 20 times more than the flow of all the world's rivers combined. Locally, in each individual region, the direction and nature of the current are also determined by the outline of the continents, temperature conditions, salinity distribution and other factors.
The Gulf Stream in a broad sense is the entire system of warm currents in the North Atlantic, the core and main driving force of which is the Gulf Stream
It is known that north of Cape Hatteras the Gulf Stream is losing stability. It exhibits quasi-periodic fluctuations with a period of 1.5-2 years, similar to fluctuations in the jet stream in the atmosphere, known as the index cycle. Considering the influence of the Gulf Stream on the climate, it is assumed that in the short-term historical perspective a climate catastrophe associated with disruption of the flow is possible.
In particular, according to Doctor of Geographical Sciences, oceanologist A.L. Bondarenko, “the mode of operation of the Gulf Stream will not change.” This is argued by the fact that no actual water transfer occurs, that is, the flow is a Rossby wave. It carries heated water masses from the Indian Ocean and the south Atlantic to the northwestern coast of Europe.
But the North Atlantic Gulf Stream can't explain all the disappearances
Thanks to the Gulf Stream, European countries adjacent to the Atlantic Ocean have a milder climate compared to regions lying at the same latitude. Over the North Atlantic, westerly winds remove heat from masses of warm water and are transferred to Europe.
This current is directed in a narrow stream along the coast of North America. An additional factor of deviation in the eastern direction is the Coriolis force. The continuation of the Gulf Stream to the northeast of the Great Newfoundland Bank is the North Atlantic Current.
Now the Gulf Stream for Europe and the USA is a generous gift of nature to their economies and populations.
The northern hemisphere weather kitchen is located in the North Atlantic and Arctic Ocean. The Gulf Stream acts as a heating system in it; it is also called the “stove of Europe”. The cold and denser Labrador Current “dives” under the warm and lighter Gulf Stream without preventing it from warming Europe.
The density of the Labrador Current waters is only 0.1% higher than the density of the Gulf Stream waters. As a result, the Barents Sea does not freeze all year round, and in Europe palm trees grow and houses with cardboard walls are built. If suddenly the Labrador Current becomes equal in density to the Gulf Stream, it will rise closer to the surface of the ocean and block its movement to the north. That's it, we've arrived. We get a diagram of ice age currents.
Studies of ice in Greenland show that climate change processes could occur within three to ten years. Over the next few years, air temperatures in Europe will be equal to those in Siberia. Now giant oil spills have been discovered in the waters of the Gulf of Mexico. Oil has been leaking for months from a well drilled by BP on the bottom of the Gulf of Mexico.
The Norwegian Current disappeared along with it. The first to report the stoppage of the Gulf Stream in August 2010 was Dr. Zangari, a theoretical physicist from Italy. The average water temperature in the north of the Gulf Stream dropped by 10 degrees.
The Gulf Stream is a warm current in the Gulf of Mexico that bends around Florida and flows along the east coast of the United States to approximately 37 degrees north latitude. and then breaks away from the coast to the east
Letters are coming to the editor asking for clarification on whether the warm current will really disappear soon. Similar currents exist in the Pacific Ocean - Kuroshio, and in the Southern Hemisphere.
For the same reason, the Northern Hemisphere as a whole is slightly warmer than the Southern. The primary reason for the unusual nature of the North Atlantic is that slightly more water evaporates over the Atlantic than falls as precipitation.
In place of the water that has sank into the depths of the North Atlantic, water comes from the south, this is the North Atlantic Current. Thus, the causes of the North Atlantic Current are global, and are unlikely to be significantly affected by such a local event as an oil spill in the Gulf of Mexico.
But even this magnitude of seasonal anomalies is quite common and is observed in one region or another almost every year. Reports that the Gulf Stream between the 76th and 47th meridians in 2010 became colder by 10 degrees Celsius are also not confirmed. But the ice continued to melt, and at some point, water from the lake began to flow into the North Atlantic, desalinizing it and thereby preventing the sinking of the water and the North Atlantic Current.
A continuation of the Gulf Stream is the North Atlantic Current, carrying a cooled stream in the north to the Southern Hemisphere. Changes in the continuity of the Gulf Stream are a topic of debate in scientific circles. Several factors are involved in the origin and direction of the Gulf Stream. Almost a third is in the path of the Gulf Stream. The first refers to the Gulf Stream itself - an ocean current along the eastern coast of North America up to 90 kilometers wide and with a speed of up to several meters per second.
Oceans, lakes and rivers
Gulf Stream Current
In Western Europe, as well as in east coast The USA climate is quite mild. So on the Florida coast average temperature water very rarely falls below 22° Celsius. This is during the winter months. In summer, the air heats up to 36°-39° Celsius with humidity reaching 100%. This temperature regime extends far to the east and north. It covers the states: Arkansas, Alabama, Mississippi, Tennessee, Texas, Kentucky, Georgia, Louisiana, as well as North and South Carolina.
All these administrative entities lie in an area of humid subtropical climate, where the summer average daily temperature does not fall below 25° Celsius, and in the winter months it very rarely drops to 0° Celsius.
If we take Western Europe, then the Iberian, Apennine and Balkan peninsulas, as well as the entire South part France are located in subtropical zone. Summer temperatures there range from 26°-28° Celsius. In winter, these indicators drop to 2°-5° Celsius, but almost never reach 0°.
In Scandinavia, the average winter temperature ranges from minus 4° to 2° Celsius. In the summer months it rises to 8°-14°. That is, even in the northern regions the climate is quite acceptable and suitable for comfortable living.
Gulf Stream Current
This temperature bliss occurs in a huge region for a reason. It is directly connected with the Gulf Stream ocean current. It is what shapes the climate and gives people the opportunity to enjoy warm weather almost all year round.
The Gulf Stream is a whole system of warm currents in the North Atlantic Ocean. Its full length covers a distance of 10 thousand kilometers from the sultry shores of Florida to the ice-covered islands of Spitsbergen and Novaya Zemlya. Huge masses of water begin to move in the Strait of Florida. Their volume reaches 25 million cubic meters per second.
The Gulf Stream moves slowly and majestically along the east coast of North America and crosses 40° N. w. Near the island of Newfoundland it meets the Labrador Current. The latter carries cold waters to the south and forces warm water flows to turn east.
After such a collision, the Gulf Stream splits into two currents. One rushes north and turns into the North Atlantic Current. This is what shapes the climate in Western Europe. The remaining mass reaches the coast of Spain and turns south. Off the coast of Africa, it meets the North Trade Wind Current and deviates to the west, ending its journey in the Sargasso Sea, from which it is a stone's throw to the Gulf of Mexico. Then the cycle of huge masses of water repeats.
This has been going on for thousands of years. Sometimes a powerful warm current weakens, slows down, reduces heat transfer, and then cold falls on the ground. An example of this is the Little Ice Age. Europeans observed it in the XIV-XIX centuries. Every heat-loving resident of Europe has experienced first-hand what a real frosty, snowy winter is like.
True, before this, in the 8th-13th centuries there was a noticeable warming. In other words, the Gulf Stream was gaining power and releasing a very large amount of heat into the atmosphere. Accordingly, on the lands of the European continent the weather was very warm, and snowy, cold winters had not been observed for centuries.
Nowadays, powerful warm streams of water also influence the climate as in old times. Nothing has changed under the sun, and the laws of nature remain the same. But man has come very far in his technological progress. His tireless activities triggered the Greenhouse Effect.
The result was the melting of the ice of Greenland and the Arctic Ocean. Huge masses of fresh water poured into salt waters and headed south. Nowadays, this situation is already beginning to affect the powerful warm current. Some experts predict an imminent stop of the Gulf Stream, since it will not be able to cope with the influx of incoming waters. This will entail a sharp cooling in Western Europe and the east coast of North America.
The situation was aggravated biggest accident on oil field Tiber in the Gulf of Mexico. Underwater in the bowels of the earth, geologists have found huge oil reserves, estimated at 1.8 billion tons. Experts drilled a well, the depth of which was 10,680 meters. Of these, 1259 meters were in the ocean water column. In April 2010, a fire broke out on an oil platform. It burned for two days and claimed the lives of 11 people. But it was, although tragic, a prelude to what happened after that.
The burnt platform sank, and oil began to flow from the well into the open ocean. According to official sources, 700 tons of oil entered the waters of the Gulf of Mexico per day. However, independent experts gave a different figure—13.5 thousand tons per day.
The oil film, huge in its area, hindered the movement of Atlantic waters, and this, accordingly, began to negatively affect heat transfer. Hence, there was a disruption in the circulation of Atlantic air flows. They no longer had the strength to move east and create the usual mild climate there.
The result was a terrible heat wave in Eastern Europe in the summer of 2010, when air temperatures rose to 45° Celsius. Provoked similar winds from North Africa. They, without encountering any resistance on their way, brought a hot and dry cyclone to the north. It hovered over a vast territory and stayed above it for almost two months, destroying all living things.
At the same time, Western Europe was shocked by terrible floods, as heavy, moisture-filled clouds coming from the Atlantic did not have enough strength to break through the dry and hot front. They were forced to dump tons of water onto the ground. All this provoked a sharp rise in river levels and, as a result, various disasters and human tragedies.
What are the immediate prospects, and what awaits old Europe in the near future? Experts say that cardinal climate change will begin to be felt in 2020. Western Europe faces cooling and rising sea levels. This will provoke the impoverishment of the middle class, as it cash invested in real estate that will plummet in value.
From here, political and social tension will arise in all layers of society. The consequences of this can be the most tragic. It is simply impossible to predict anything specific, since there are many scenarios for the development of events. Only one thing is clear: difficult times are coming.
The Gulf Stream, nowadays, thanks to global warming and the disaster in the Gulf of Mexico, has practically closed in a ring and does not provide sufficient thermal energy to the North Atlantic Current. Accordingly, air flows are disrupted. Completely different winds are beginning to dominate over European territory. The usual climate balance is being disrupted - this is already noticeable with the naked eye.
In such a situation, anyone can be overwhelmed by a feeling of anxiety and hopelessness. Of course, not for the fate of hundreds of millions of people, since this is too vague and unclear, but for the specific fate of their relatives and friends. But it is premature to despair, let alone panic. Nobody knows how it will actually be there.
The future is full of surprises. It is entirely possible that global warming is not global warming at all. This is a normal increase in temperatures as part of the climate cycle. Its duration is 60 years. That is, for six decades the temperature on the planet has been steadily increasing, and over the next 60 years it has been slowly decreasing. The beginning of the last cycle dates back to the end of 1979. It turns out that half the journey has already been completed and we only have to wait 30 years.
The Gulf Stream is too powerful a stream of water to simply change direction or disappear. There may be some failures and deviations, but they will never turn into global and irreversible processes. There are simply no prerequisites for this. At least these days they are not observed.

A warm current is... Main characteristics of currents. The most famous warm currents
The warm current is the Gulf Stream, El Niño, Kuroshio. What other currents exist? Why are they called warm? Read about it further.
Where do currents come from?
Currents are directional flows of water masses. They can have different widths and depths - from several meters to hundreds of kilometers. Their speed can reach up to 9 km/h. The direction of water flows is determined by the rotational force of our planet. Thanks to it, currents in the Southern Hemisphere deviate to the right, and in the Northern Hemisphere - to the left.
The formation and character of currents is influenced by many conditions. The reason for their appearance may be the wind, the tidal forces of the Moon and the Sun, different densities and temperatures, and the water level of the World Ocean. Most often, several factors contribute to the formation of currents.
There is a neutral, cold and warm current in the ocean. They are defined as such not because of the temperature of their own water masses, but because of the difference with the temperature of the surrounding waters. This means that the current can be warm, even if its waters are considered cold by many indicators. For example, the Gulf Stream is warm, although its temperature ranges from 4 to 6 degrees, and the temperature of the cold Benguela Current is up to 20 degrees.
A warm current is one that forms near the equator. They form in warm waters and move to colder ones. In turn, cold currents move towards the equator. Neutral currents are those that do not differ in temperature from the surrounding waters.
Warm currents
Currents influence the climate of coastal areas. Warm water flows warms up the ocean waters. They contribute to a mild climate, high humidity air and a large number precipitation. Forests form on the banks next to which warm waters flow. There are such warm currents of the World Ocean:
Pacific Ocean Basin
- East Australian.
- Alaskan.
- Kuroshio.
- El Niño.
Indian Ocean Basin
Atlantic Ocean Basin
- Irminger.
- Brazilian.
- Guiana.
- Gulf Stream.
- North Atlantic.
Arctic Ocean Basin
- West Spitsbergen.
- Norwegian.
- West Greenland.

Gulf Stream
The warm Atlantic current, one of the largest in the Northern Hemisphere, is the Gulf Stream. It begins in the Gulf of Mexico, enters the waters of the Atlantic Ocean through the Strait of Florida and moves in a northeasterly direction.
The current carries a lot of floating algae and various fish. Its width reaches up to 90 kilometers, and the temperature is 4-6 degrees Celsius. The waters of the Gulf Stream have a bluish tint, contrasting with the surrounding greenish ocean water. It is not homogeneous, and consists of several streams that can separate from the general flow.
The Gulf Stream is a warm current. Meeting with the cold Labrador Current in the Newfoundland area, it contributes to the frequent formation of fogs along the coast. In the very center of the North Atlantic, the Gulf Stream divides, forming the Canary and North Atlantic currents.
El Niño
El Niño is also a warm current - the most powerful current. It is not constant and occurs once every few years. Its appearance is accompanied by a sharp increase in water temperature in the surface layers of the ocean. But this is not the only sign of El Niño.
Other warm currents of the World Ocean can hardly compare with the power of influence of this “baby” (as the name of the current is translated). Together with warm waters, the current brings with it strong winds and hurricanes, fires, droughts, and prolonged rains. Residents of coastal areas are suffering from the damage caused by El Niño. Vast areas are flooded, leading to the destruction of crops and livestock.
The current is formed in the Pacific Ocean, in its equatorial part. It stretches along the coast of Peru and Chile, replacing the cold Humboldt Current. When El Niño occurs, fishermen also suffer. Its warm waters trap cold waters (which are rich in plankton) and prevent them from rising to the surface. In this case, the fish do not come to these territories to feed, leaving fishermen without a catch.
Kuroshio
In the Pacific Ocean, another warm current is the Kuroshio. It flows near the eastern and southern shores Japan. The current is often defined as a continuation of the Northern Trade Wind. main reason its formation is the difference in levels between the ocean and the East China Sea.
Flowing between the straits of Ryukkyu Island, the Kuroshio becomes the North Pacific Current, which turns into the Alaskan Current off the coast of America.
It has similar features to the Gulf Stream. It forms a whole system of warm currents in the Pacific Ocean, just like the Gulf Stream in the Atlantic. Thanks to this, Kuroshio is an important climate-forming factor, softening the climate of coastal areas. Strong influence the current also flows into the water area, being an important hydrobiological factor.
The waters of the Japanese current are characterized by a dark blue color, hence its name “Kuroshio”, which translates as “ black current" or " dark water" The current reaches a width of 170 kilometers, and its depth is about 700 meters. Kuroshio's speed ranges from 1 to 6 km/h. The water temperature of the current is 25 -28 degrees in the south and about 15 degrees in the north.
Conclusion
The formation of currents is influenced by many factors, and sometimes a combination of them.
A current whose temperature exceeds the temperature of the surrounding waters is called warm. At the same time, the water in the current can be quite cold. The most famous warm currents are the Gulf Stream, which flows in the Atlantic Ocean, as well as the Pacific Kuroshio and El Niño currents. The latter occurs periodically, bringing with it a chain of environmental disasters.
Everyone knows from school that the Gulf Stream warms entire continents. So imagine what will happen when it completely changes direction. Now this process is underway and this explains many natural disasters...
Scientists have confirmed that the famous ocean current, the Gulf Stream, has finally changed its direction. Now it does not reach Spitsbergen, but turns towards Greenland, which contributes to warmer weather on the American continent, but “freezes” northern Siberia.
The shutdown of the Gulf Stream was first reported by Dr. Dr. Gianluigi Zangari, a theoretical physicist at the Frascati Institute in Italy, in a journal article on June 12, 2010. The article is based on satellite data from the Colorado Aerodynamic Research Center, coordinated with the US Navy's National Oceanic and Atmospheric Administration . The author pointed out the stopping of the rotation of water flows in the Gulf of Mexico and the breaking of the Gulf Stream into parts. Subsequently, the images were changed on the server of the Colorado Aerodynamic Research Center and now it is difficult to say by whom and when.
How did the current go?
The cold and denser Labrador Current “dived” under the warm and lighter Gulf Stream, without preventing it from warming Europe, reaching Murmansk. Then the Labrador Current “surfaced” off the coast of Spain under the name of the cold Canary Current, crossed the Atlantic, reached the Caribbean Sea, heated up and, passing through a loop in the Gulf of Mexico, already under the name of the Gulf Stream, freely rushed back to the North.
The Gulf Stream was part of the thermohaline circulation system, a key element in the planet's thermal regulation. It separated England and Ireland from becoming a glacier. Smoothed out the climate in the Scandinavian countries.
After Dr. Zangari's message, the Canadian Parliament created a commission to find out the real state of affairs with the Gulf Stream near the coast of the state. It was headed by the famous US oceanologist Ronald Rabbit, a technologist for processing the biomass of the World Ocean and improving the environment. A special dye that does not harm the flora and fauna of the ocean was poured into containers that exploded at a certain depth and, thus, the flow of movement of water masses was tracked. The Gulf Stream was not discovered as an existing current.
But, as it turned out, the self-regulating system called “worked” this time too. According to research, the current “crept” 800 miles (1,481 kilometers) east of the former Gulf Stream zone. According to satellite images, the temperature of this current has increased relative to the Gulf Stream. This means that the evaporation rate in the warm zone above the ocean has increased.
A small digression: most people believe that moist air is heavier than dry air, but this is not true. Molecules of oxygen O2, carbon dioxide CO2 and nitrogen N2 are heavier than water molecules H2O.
What does this change mean for us?
Presumably, a very cold winter of up to -45 degrees and little snow in the European part of Russia, Western Europe will be covered with snow, and hurricane winds will rage on the border of the fronts. In mid-February 2011, instead of frost, spring came in Canada with a temperature of +10. America, apparently, will also not be left without a “carrot”. This is confirmed by the recent cold weather in Montana, South Dakota, Texas, Arkansas and Tennessee.
Main world ocean currents. The Gulf Stream originates in the Gulf of Mexico, heads towards Europe (dark color of the “river”), turns towards Greenland, cools (gray, light color"rivers"), plunging to depth and flowing south. According to new data, the channel of the Gulf Stream (surface warm flow) has deviated beyond Lately towards Greenland 800 km.

The Gulf Stream (from the English gulf stream - current from the bay) is called a warm ocean current in the Atlantic Ocean. It carries heated water masses from the Indian Ocean and the south Atlantic to the northwestern coast of Europe. A continuation of the Gulf Stream is the North Atlantic Current, carrying a cooled stream in the north to the Southern Hemisphere. Thanks to the Gulf Stream, European countries adjacent to the Atlantic Ocean have a milder climate compared to regions lying at the same latitude. Over the North Atlantic, westerly winds remove heat from masses of warm water and are transferred to Europe.As a result of the action of this natural thermal contour, deviations of air temperature from average latitude values in January reach 15-20 °C in Norway, and more than 11 °C in Murmansk. The volume of water carried by the Gulf Stream is 50 million cubic meters every second (!), which is 20 times more than the flow of all the rivers on the planet combined. The thermal power of this current is approximately 1.4 × 1015 watts.
Several factors are involved in the origin and direction of the Gulf Stream. Among them, the most significant are atmospheric thermal circulation and the Coriolis force resulting from the rotation of the Earth. The predecessor of the Gulf Stream, the Yucatan Current, flows from the Caribbean Sea to the Gulf of Mexico through the strait between Cuba and the Yucatan Peninsula. There, the flow is divided into two parts - one goes along the circular current of the bay, and the second forms the Florida Current and is directed through an even narrower strait between Cuba and Florida, and then exits into the Atlantic Ocean. The water masses of the Florida Current, heated in the Gulf of Mexico, unite near the Bahamas with the Antilles Current and ultimately form the Gulf Stream. This current is directed in a narrow stream along the coast of North America. At North Carolina level, the Gulf Stream departs from coastal zone and turns into the open ocean. About 1,500 km further, it encounters the oncoming cold Labrador Current, deflecting it even further east towards Europe. An additional factor of deviation in the easterly direction is the Coriolis force. On the way to Europe, some of the heat is lost due to evaporation, cooling and numerous side branches that reduce the main flow, but enough heat still comes to Europe to create a mild climate in it that does not correspond to the latitudes. The continuation of the Gulf Stream to the northeast of the Great Newfoundland Bank is the North Atlantic Current. The average water flow in the Strait of Florida is 25 million m 3 /s.
The slowing of the Gulf Stream around 1300 was one of the main causes of the Little Ice Age in Europe. Now the Gulf Stream for Europe and the USA is a generous gift of nature to their economies and populations. But not everything looks so rosy in the near future. The northern hemisphere weather kitchen is located in the North Atlantic and Arctic Ocean. The Gulf Stream acts as a heating system in it; it is also called the “stove of Europe”. The cold and denser Labrador Current “dives” under the warm and lighter Gulf Stream without preventing it from warming Europe. Then the Labrador Current “emerges” off the coast of Spain under the name of the cold Canary Current, crosses the Atlantic, reaches the Caribbean Sea, heats up, and now under the name Gulf Stream freely rushes back to the North. Thus, it is the density of water in the Labrador Current that is key factor current temperature balance. The density of the Labrador Current waters is only 0.1% higher than the density of the Gulf Stream waters. As a result, the Barents Sea does not freeze all year round, and in Europe palm trees grow and houses with cardboard walls are built. If suddenly the Labrador Current becomes equal in density to the Gulf Stream, it will rise closer to the surface of the ocean and block its movement to the north. That's it, we've arrived. We get a diagram of ice age currents. The Gulf Stream warms Spain instead of Great Britain, and the cold Labrador Current freezes Europe.
Studies of ice in Greenland show that climate change processes could occur within three to ten years. Over the next few years, air temperatures in Europe will be equal to those in Siberia. Already, the strength of the winter Gulf Stream towards Europe is weakening significantly (according to some data, by 30%). Probably, the abnormally cold winters of recent years in Europe - direct consequence this.
The accelerator of this process was the accident oil platform in April 2010 in the Gulf of Mexico. Now giant oil spills have been discovered in the waters of the Gulf of Mexico. Oil has been leaking for months from a well drilled by BP on the bottom of the Gulf of Mexico. To reduce the gigantic fines calculated by the size of the spot on the surface, BP managed to hide most oil. With the help of binding reagents, she... was lowered to the bottom. As a result, a blood clot formed in the water column, as if in blood vessel, slowing down the normal circulation of water.
According to the latest satellite data, the North Atlantic Current no longer exists in its previous form. The Norwegian Current disappeared along with it. The first to report the stoppage of the Gulf Stream in August 2010 was Dr. Zangari, a theoretical physicist from Italy. He has been collaborating for several years with a group of scientists monitoring the Gulf of Mexico. According to him, "... great amount oil, constantly expanding in volume, covers such vast areas that it has a serious impact on the entire thermoregulation system of the planet by destroying the boundary layers of the warm flow of water. The Gulf of Mexico pipeline ceased to exist a month ago, the latest satellite data clearly shows that the North Atlantic Current is now gone and the Gulf Stream is beginning to break apart 250 km offshore North Carolina. The situation where warm waters flow through cooler ones has a large effect not only on the ocean, but also on the upper atmosphere up to seven miles high. The absence of this usual phenomenon in the eastern North Atlantic disrupted the normal course of atmospheric flows this summer. As a result, unheard-of high temperatures in Moscow (up to 40C), droughts and floods in Central Europe and massive floods in China, Pakistan and other Asian countries.”
The average water temperature in the north of the Gulf Stream dropped by 10 degrees. The conveyor belt broke into separate sections and stopped transporting warm water to Europe. Dr. Zangari states: “They killed the pacemaker of the global climate on the planet.”
The strongest cold weather in the last 100 years came to Europe last winter. Both airports were closed for a time, and icy winter rains hit Moscow and the region. What can we expect this coming winter?
