Distinguish the gym, lower and common blizzard. The blizzard is the transfer of snow by the wind. It may be observed both in cloudless weather and at the snowfall. The low-level blizzard is the transfer of snow by the wind from the surface of the snow cover in a layer of a thickness of several meters. Misel, Sorokin Vladimir Georgievich.
Some authors belong to the blizzard transfer of snow dropping out of the clouds, and has not yet affected the earth's surface. They distinguish the so-called horse-in blizzard - snowfall during wind, when snowflakes move along with the air flow until the turn of the earth's surface, where they remain motionless.
Blizzard and blizzard - is this one and the same?
The intensity of the snowstorm depends on the speed and turbulenceless flow stream, the intensity of the snowfall, the shape and size of the particles of snow, temperature and humidity of the air. The total solid flow consumption is equal to the mass of snow, transferred through one meter of the front of the snowmate along the surface of the earth for 1 second. The following types of blizzles allocate the following types of snowstore.
Low snowstocks can be saturated or unsaturated, depending on whether the wind stream transfers the amount of snow that corresponds to its maximum transporting ability. In the total blizzard there are all three ways to transfer simultaneously with the fall of atmospheric snowflakes.
With weak missiles, snow ripples occurs, like ripples of sand vegans and sandy shames. During the blizzard, the transfer of steam and heat in the snow cover occurs in tens of times stronger than in their absence. It limits the height of the snow diffusion layer during the blizzard.
In the field of the blizzard, you can find places where snow transfer begins. Thus, an unsaturated blizzard acts in the acceleration zone, which sweats all the snow on its path, dense. In this zone there are such forms of snow microrelief as rustling and wind grooves. The blizzard is usually called a strong low-level blizzard. In the Asian regions, a strong overall blizzard at low temperature is called buran.
How to behave in blizzard and Purg
The appearance of the lower snowstorm leads to impairment of visibility (at an altitude of two meters, it usually drops to 2-9 km, sometimes to several hundred meters). Vertical visibility practically does not deteriorate, which allows you to determine the state of the sky. The lower blizzard may occur both in cloudless weather and in the snowfall.
It is often observed before or after blizzard, or in the case of a remote blizzard. The hydrometeorological service of such a term does not know, and in scientific meteorological literature it is never used. In the explanatory dictionary of Vladimir Dalya Vyuga - the word, a relatively blizzard, along with a notch, Vyalitsa, Volokuchi, Tear, Lonely and Popolzha.
Apparently, the blizzard and blizzard are nearby concepts, but it is officially customary to use the word "blizzard", "blizzard" is the national name of a natural phenomenon. Blizzard is one of the lobby hat, the same as Buran, a snowy drift or a blizzard. Do not confuse a snowfall blizzard when snowsets fall out of the clouds. The blizzard may be accompanied by snowfall, but its most important difference is the wind, lifting up lying snow or chanding snow falling.
In most cases, just such a thing as the low-level blizzard, and is referred to as the people of the blizzard. The intensity of the blizzard is usually such that in the vortex flow there are already fragments of snowflakes, while in the total snowflake snowflakes almost always retain their integrity.
The blizzard provokes the variability of the wind, which begins to blow sharply in one, then in the other direction, causing snow curvatures. The blizzard more often arises above the uneven terrain of the area, the blizzard goes over a smooth earth surface. With a blizzard, the snow is lowered unevenly, with snowstorming - a fairly homogeneous layer of not too much density.
Probably, each of us was brought in winter to get into a strong blizzard. But one thing to feel a blizzard, and quite another - to have a whole basis of knowledge devoted to this natural weather. So, what are blizzards from the point of view of concepts of meteorology and Russian language? Let's figure it out in detail in the intricacies of this beautiful, but at the same time dangerous phenomenon of nature. From a scientific point of view, a blizzard is called the transfer of snow masses above the surface of the Earth through a powerful and impetuous wind. This is a natural phenomenon characteristic for winter time.
Mandatory condition - wind speed from 5 to 6 meters per second and more powerful. But if you compare it with a common blizzard, the lower snowstorm only raises the snow from the ground and never spreads on the sides of the snow masses coming from the clouds. By the way, sometimes in the people it is called a white blizzard.
Not really. Let's repeat again: the blizzard is the transfer of snow over the ground through a powerful and impetuous wind. In this case, the snow is usually moving in one direction. The loyalty can not even be called a variety of blizzards, because it is a completely independent phenomenon. For example, "Burana" the Turkic names of the names, because in the steppes of the Volga region and in the eastern part of Russia, blizzards are usually so called.
In general, blizzards possess a fairly insidious character, they begin spontaneously, quite quickly turning into powerful sometimes unmanaged winds, therefore it is not so easy to predict this phenomenon. When the wind power ranges from 15 to 20 m / s, then the snow can shoot in the air to a height of up to several meters, such a blizzard is called the lower.
The strongest blizzards are noted when passing deep southern cyclones. Sometimes blizzards arise in the rear of the cyclone, during the passage of cold fronts. The number of days with gaves on average over the territory is from 1 to 6. Games, usually, do not bring so much harm as a blizzard. On the elevations of the northern regions of Moldova, there are about 10 days with a blizzard.
Aspects of risk. In most cases, the snowstorm is accompanied by the fallout of snow, which significantly worsens visibility. In the winter of the next 1967, a similar blizzard was observed in the period February 11-13. He caused strong blizzards and abundant snowfalls, especially in the southern and central regions of the republic. Snow loss was accompanied by a strong wind of the northern direction, the speed of the places reached 25-28 m / s. Snowfalls and blizzards led to snow drifts on the roads of important national significance.
This is possible if the snow is dry and not fatal, and the wind speed is at least 5-6 meters per second. And in February, the blizzards will raise the blizzards. Horizontal visibility at the level of 2 m. Makes 10 km or more). Let's start with a snowstorm. In any case, this is a strong blizzard. The blizzard intervened on the fate of young lovers. At the same time, the blizzard is different.
All these concepts are associated with the intensity of the wind stream, but it is this intensity that they differ. It is also worth noting that the same phenomenon is called different words in different regions. Therefore, they can be called synonyms. Consider each of these concepts.
Blizzard- Transferring snow by the wind in the surface layer of air. Snow can rise as previously fallen, and accompanied by snowfall.
In addition, the blizzard happens:
in the form of losses - the transfer of non-aggated snow, usually without snowfall and in the air layer to 2 m from the surface of the Earth, without a noticeable reduction in horizontal (distance) and vertical (up) visibility at wind speed of 5-6 meters per second;
low snowstorm - maybe at snowfall, but occurs in a more "thick" air layer (several meters) and is characterized by a noticeable deterioration in horizontal visibility, good vertical visibility, and wind speed 6-10 m / s;
total blizzard - Most often with snowfall, in the "thick" air layer, with wind speed above 10 m / s and very low horizontal and vertical visibility.
Blizzard- This is a strong low-level blizzard, usually on a flat chamber of the terrain, with a decrease in temperature. It differs from the snowstorm with a more intense raising of the snow already dropped with the help of cold wind. Very often, this phenomenon can be observed with a cloudless sky. This concept is used more rarely than blizzard or blizzard.
Winter storm- A strong wind stream, in which the snow rises and spins in the air.
Buran- Steppe blizzard arising with a strong northern wind. During Burana, a very large amount of snow is transferred and practically "knocks down." Very often during the burana, the trees are rooted with roots, breaks off covers on the roofs, etc.
All of us since childhood are familiar to the lines from the poem A.S. Pushkin called "Winter Morning", in which the evil blizzard-saved in the evening is characterized as the mound, bearing on the "mutal sky." And the brilliant Russian poet has also known to us from the school program, the romantic story "Blizzard": the fateful weather phenomenon accidentally connects the people of two unfamiliar people. What is this - blizzard and blizzard, and how do they differ? And maybe this is the same thing of nature? Let's try to figure out.
Definition
Blizzard- transferring over the earth's surface of snow masses with a powerful, impetuous wind of sufficient strength, and the movement of snow usually occurs in one direction.
Winter storm- Snowy Winter Storm, accompanied by a strong wind, at which the snow is spinning and rushing through the air.
Comparison
The question is ambiguous. According to many dictionaries, blizzards and blizzards are synonyms, that is, the blizzard is a variety of blizzards. In general, the word "blizzard" is used mainly in everyday household speech and artwork. The hydrometeorological service of such a term does not know, and in scientific meteorological literature it is never used. In the explanatory dictionary of Vladimir Dalya Vyuga - the word, a relatively blizzard, along with a notch, Vyalitsa, Volokuchi, Tear, Lonely and Popolzha. Moreover, Dal shares two concepts: "M itel "(buran from above) and" m e.tel "(buuran below).
Apparently, the blizzard and blizzard are nearby concepts, but it is officially customary to use the word "blizzard", "blizzard" is the national name of a natural phenomenon. Blizzard is one of the lobby hat, the same as Buran, a snowy drift or a blizzard. Do not confuse a snowfall blizzard when snowsets fall out of the clouds. The blizzard may be accompanied by snowfall, but its most important difference is the wind, lifting up lying snow or chanding snow falling.
The blizzard can manifest itself in different ways. It is capable of starting like a light winter landmark and gradually turn into a strongest buran. Meteorologists distinguish between three types of blizzards: gym, low-level blizzard and the so-called overall blizzard. During a gym lying on Earth, snow rises and immediately transferred to the wind at a height of no more than two meters. This is possible if the snow is dry and not fatal, and the wind speed is at least 5-6 meters per second. The lower flower is fixed when the wind transfers the snow masses in a layer of several meters high. The wind speed is at the same time at least 7-9 meters per second. There is also the concept of "common blizzard" when the wind transfer to the snow becomes so intense that it is impossible to determine if there is snowfall or moves in space only the snow raised from the ground. In this case, visibility is very bad, it is impossible to see the sky and clouds, and the wind speed is from 10 meters per second.
In most cases, just such a thing as the low-level blizzard, and is referred to as the people of the blizzard. The intensity of the blizzard is usually such that in the vortex flow there are already fragments of snowflakes, while in the total snowflake snowflakes almost always retain their integrity. The appearance of the blizzard largely depends on the terrain: as a rule, it most often occurs above the uneven surface. The blizzard provokes the variability of the wind, which begins to blow sharply in one, then in the other direction, causing snow curvatures. During the blizzard, the snow is deposited on earth unevenly, somewhere in large masses, and somewhere - a thin layer. When snowstorming layers of snow are fairly homogeneous and characterized by the same, not too high density. Also, in a snowstorm, pecked snow particles are larger than with a blizzard. The blizzard is more often observed in cyclonic weather (with reduced atmospheric pressure), and blizzard - with anticyclonic (with high pressure).
Conclusions Site
- Blizzard and blizzard are nearby concepts, but a blizzard is a scientific, official meteorological term, and blizzard - a folk name of blizzards.
- In a common sense, the term "blizzard" in most cases is used when a powerful, impetuous wind moves snow masses over the ground in approximately in one direction. About the blizzard they say when a strong changeable wind begins to twist the vortex streams, as a result of which the snow spins and rumbles through the air in all directions.
- The blizzard more often arises above the uneven terrain of the area, the blizzard goes over a smooth earth surface.
- With a blizzard, the snow is lowered unevenly, with snowstorming - a fairly homogeneous layer of not too much density.
- With a blizzard in the air, there are already fragments of snowflakes, with a blizzard, many of them retain their original shape.
- The blizzard is more often observed in cyclonic weather, the blizzard is characteristic of anticyclone.
The blizzard is a natural phenomenon that can be manifested in different ways: from light winter landing to bouran and snowy drifts. To understand all the intricacies and features of this beautiful, but dangerous phenomenon, the following information from the site can help.
What is a blizzard?
In meteorology, there is a clear definition of a blizzard - this is the transfer of snow masses above the surface of the earth with a gusty and strong wind. Billows are common, gym and lower. If the so-called "common blizzard" goes outside the window, this weather phenomenon will definitely be accompanied by the fallout of snow, so such a cunning is most dangerous. The low-level blizzard, unlike the total, raises the snow from the ground, this weather phenomenon can be with clear weather, without falling out additional snow. A gym is a special kind of lower snowstorm, but during her the snow flies almost on the ground, not rising high.
The blizzard can manifest itself in a wide variety of horses - from Burana to snowy drifts, blizzards and purpons, there is also a steppe blizzard characteristic of many regions of our country.
Huge masses of horizontally flying snow are most dangerous, which makes breathing, movement and visibility, which in some cases does not exceed 5 meters. Such snowy drifts may occur not only in winter, but also early in spring. Spring snowy tumans are especially dangerous, as they lead to sticking of wet and heavy snow on the branches of trees, power wires, vehicles and residential buildings, which can lead to life-threatening consequences.
Strong blizzards are capable of harmful to many areas of the economy, especially for agriculture, as the impusty, powerful winds blow snow from the fields, thereby creating a dangerous threat to the freezing of winter crops. The most destructive situation when the blizzard is not one, but a few days, then its consequences are particularly negative.
How are blizzards formed?The emergence of snow blizzards is due to the activities of atmospheric fronts and cyclones. Particularly strong blizzards generate southwestern and southern cyclones, bringing in our latitudes warm, wet air from the Atlantic, which moves towards the Arctic frosty air. Such an eternal confrontation of the North and the South and gives rise to heavy snowfall with gusty and strong winds, as a result of which snow blizzards are formed - such a natural phenomenon is often familiar in our country.
Interestingly, blizzards are most often formed in the northern regions of our country. This is explained by the fact that in the northern zones, the snow falls at lower air temperatures than over the European part of the Russian Federation. Snow in the north has a slightly different structure: it is lighter and small, and therefore it easily takes up up even with small gusts of the wind.
Wind, the speed of which is 5 meters per second, are able to cause a gym. Therefore, the famous Siberian and Ural Buranes differ from European fine and dry snow, as well as low temperature regime. With snowstorms, the wind speed can be 25-30 meters per second, and if it comes to blizzards in open areas, for example, in the tundra, then the wind speed can reach the indicator of 40 meters per second. Very often, active cyclones and cold fronts bring strong blizzards, which are precursors to reduce temperature.
Blizzard varieties.
In our country, snowstorms may have different names based on the terrain where these weather phenomena will occur.
The strongest snowy blizzards observed, mainly in the north of Russia, are called Purga. Rather, this is not an official scientific name, but a jargonism that people residing in these regions, meaning strong snow blizzards.
The steppe blizzard is called Buran. Such weather phenomena is characteristic of Bashkortostan, Kazakhstan, the Orenburg region, the steppe part of the Crimea and the South of Ukraine.
Blizzard with strong wind is called blizzard. This phenomenon of nature is often found on the European part of Russia.

Very interesting winter character - Marzhana.
Marzhana is a spring ritual character, the scarecrow-embodiment of death and winter, which was treated to provide a crop.
the winter deities are also
IN LITERATURE.
The invisible old woman-winter was already somewhere nearby, her cold chain fingers penetrated under the casing, taped, sprinkling all the body with a shudder, pinching his nose and ears. And what else will be in the student and the request, when her sons of snow fabric and bounds come to the help of Zimerzel, fierce winter perfumes, able to get up all the lives to death! ..
"She's all gray herself, in her hair her blizzard hides, in the sleeves, the fur coats will be born," the princess told, pressing his son's head to her side and sleeves of a fur coat hiding him from falling snowflakes. - She herself humpback, evil, greedy. It would be all the white light with snow to fall asleep, all the rivers beaten, all the people are freeze! She is the most native sister. From them, yes from Mary and Moroka all the darkness on Earth, all cold, illness and death itself.
E. Dvoretskaya, Amber Eyes Forest
Zimerzla - the harsh winter deity of the ancient Slavs. It breathes with cold and frosts. Her clothes are Tulup from Inea. Frosts - her children, they are a crown of ice kuyu, earrings from icicles. People appealed to the zimerzel asking not to chop the home, do not freeze crops.
Winter storm, couch - Ukrainian folk character.
"Clear is a beautiful, big, cheerful Molod. Couch is dressed in white, snow, with a gray collar, ramped with embroidery casing, spinning with a rotary belt, in white boots, twisted in the mark, and does not have a mittens.
She, by order of her husband, Snowy with his children spreads snow, shelters all the land so that the heat was land, so that the roots of the plants are not extincting the roots, shelters-covers all the roads so that it was good to ride the sleigh ... " (Stepan Kilimnik).
Although turns the blizzard, it makes the way, and sometimes the drifts will take up to the roof, still loves to have fun. Slogs the earth with snow and rushes together with the defone on sledding or skating.
"Metelitsa is a young girl, in a white wreath, with white ribbons, in a couste, 10-12 turns of an expensive pearl necklace, with loose braids, very cheerful, beautifully dancing, in shiny boots, with silver boots"(Stepan Kilimnik).
Metelitsa blizzard - Daughter blizzard and snowy. She collects all the snowforce together, and they " mischititsa " - Dance. And she herself dances best "... played by snow, throws him, then sweeps them, then turns, it throws people into the eyes"(Stepan Kilimnik).
"Snow is a folk character of Ukrainians. This is a fit of the uncle, beautifully fitted in the scroll, in the same cap and mittens, like Santa Claus. And the snow itself is all white, out of snow, and accompanied by a dense fog of snow, not to see it " (Stepan Kilimnik).
Snowman comes to the call of winter, it gets on the mountain or on the cloud, takes a big shovel in the hands and, when the winter or frost come to him - sows the snow to the ground, "... like a peasant sometime rye sowed". And snow flies on all directions.
Snowy densely shelters the land so that it was warm for her, heats her so that nothing in the ground was extinct. Trying snowy enough of the snow to inspire that the spring earth is drunk, for it does not drink in a whole winter. But the snow is afraid of spring. Only she gets warm, he sits on a gray cloud, collects his bags with snow and flies north. There replenishes snow reserves, prepares for the next winter. Friends with snow with winds that help him in work. And he also loves a blizzard and blizzard, for no one is better than their snow on the ground disks.
