Many from time to time are thinking - how accurate weather forecasts? Whose weather forecast is more accurate? Which way is most often mistaken forecasts for my city?

Time of mathematical adventures!


For the past few years, Yandex actively develops its weather service. A couple of years ago, methum technology and precipitation prediction was presented with an accuracy of minutes.

In the discussion to these publications, Fantast8 comments were allocated. The "meteorologist-amateur" in a rather aggressive form pounced to criticize Yandex technology and if not paying attention to the style of communication, then the essence of the claims were reduced to the absence of invoice and closures of statistics.

And then I was thinking: Does anyone generally consider the accuracy of the forecasts?

Fire kingdom

The ForecastAdvisor project was issued rapid google, but the forecasts were estimated exclusively in US cities, and naturally there were no Russian-speaking providers (Yandex, hydromet, etc.).

In runet, for some time there was a project MyCli.me, now closed. However, he had constant data collection issues and the rating system (the choice of the best forecast) was not based on the scientific method.

In addition, I found a lot of endeavors, for example, from OLS and Lucius, but they were all limited or in time, or around the city, or on the provider. For example, one of the most amazing projects from SLIMYHORROR analyzes the projections of the following 5000 days in a row! But only BBC forecasts are evaluated and only for UK cities.

Thus, it was decided to make your project. The case is for small - collect forecasts, collect actual weather and evaluate sales based on a scientifically based formula. From her and let's start.

Bananova Guardi

In 2009, the Hydrometeorological Center of Russia issued "manual instructions on short-term forecasts." According to this guide, the forecast is considered to come true if it differs from the actual observed temperature is no more than 3 ° C in any direction. If the outlook differs from actual weather than 3 °, then such a forecast is considered unnecessary (paragraph 7.3.1.4 of the instruction).

Read more about gradation.

Theoretically, the provider could predict the weather from -60 every day to +60 and thus get one hundred percent sales. However, the correct gradation of the forecast is the deviation of no more than 1 degree, for example, "Temperature in the afternoon from 2 ° to 4 °". Thus, a deviation is allowed to 2 degrees from the interval or 3 degrees from the value.


Weather forecasts should be assessed separately for day and night (7.2.3). The justifiedness of the daily forecast is defined as the average of the values \u200b\u200bof justifying forecasts for the night and on the day. Evaluation of the success of the weather forecasts for the calendar period (month, season, year, etc.) is to calculate their average justifies for the corresponding period (9.1.1).

Okay, it seems not difficult - we take the forecast for tomorrow (on the day after tomorrow), we collect data on actual weather, compare separately for the day and night. If a

Math.abs (PREDICT - ACTUAL)\u003e 3
then the forecast did not come true (pt \u003d 0%) if<= 3 то Pt=100%. Считаем среднюю оправдываемость за соответствующий период и получаем нужные данные.

Dark cloud

From the participants of sites with the weather immediately refused, because HTML parsing is not distinguished by stability and it will inevitably increase the number of errors in the final statistics. Fortunately, many providers provide API to access their forecasts. At the first stage, I added forecasts from Accuweather.com, Darksky.Net, Openweathermap.org and WunderGround.com. All of them provide JSON-API. In the second stage, Norwegian Yr.No with the XML-API, the Russian Hydrometeorological Center (RSS) and Yandex flashed were added.

To date, there is an agreement with foreca.com and negotiate with Gismeteo.ru, Intellicast.com and English MetOffice. If you have familiar in these projects, ready to help with the API, write!

Elevated oddity

In the theory with the collection of actual weather there was no problem. In each major city there is a weather observation station, usually in the city center, for example, in Moscow is VDH. National Hydrometeorological Services transmit data from these stations to the World Wide Weather Service, where it is processed and stored. Observations are transmitted as a synop code every 3 or 6 hours.

In addition, every major airport has a weather monitoring station, which every hour (or half an hour) transmits the weather report on the weather in Metar format.

Raw Synop and Metar data can be found on the NOAA website; Proced data on Ogimet.com. The stations themselves are convenient to search for Weatherobs.com.

However, there are several problems. First, the quality of the transmitted data - there are often typos in the summary (for example, the letter O instead of the figure 0). Secondly, data stability. In 2017, Aviamettelecom stopped the transfer to the international exchange of metelements with more than fifty airfields of Russia for a whole month. Thirdly, there are cities in which I was simply failed to find a running station. For example, in Rostov-on-Don there is no data in any station 34730 (URRR), nor in station 34731.

In such situations to collect actual weather, I use information from the private network of the Weather Company (now owned by IBM).

Science Rulit

As a result, it turned out the site meteotrust.com
At the moment, the data are collected for 10 cities of Russia from 7 providers. In the near future I plan to add more cities, more providers and more periods (long-term forecasts from HydrometCenter and Accuweather, forecasts for 10 days). In addition, the collection of statistics on precipitation is preparing. Assess the accuracy of precipitation forecasts is a bit more complicated than by temperature. This will be a separate post.

What are the conclusions?

OpenWeatherMap - bottom.
Accuweather, Yr.No, Darksky - Strong middling.
Yandex and WunderGround are excellent forecasts.
Hydrometeorological center is often struggling with Yandex for the first place in terms of short-term forecasts. However, there is an assumption that with an increase in the number of cities, especially foreign, the overall success of the hydrometector's forecasts will fall.

Each person since childhood understands that the weather is constantly changing, changes are felt both in air temperature and in strength and direction of the wind. There are smooth changes in the state of weather conditions, and there are those that wear a sharp and unexpected character. It depends on many conditions. The periods of changing the weather are associated with the rotation of the earth both around their axis and around the sun. Seasonal weather types are replaced by unexpected variables. Daily changes are very visible on the ground surface. Day Air temperature is always warmer than at night. Also, changes are associated with air movement from one area of \u200b\u200bthe planet to another. So the Northern Arctic winds bring cold, and the south wind changes the weather on a warmer and pleasant, but the air from the tropics can also bring humidity, and numerous precipitation.

What is the weather?

This concept denotes a description of the atmospheric state at a particular point, which distinguishes it from the term "climate", denoting averaged indicators of the state of the atmosphere of the region for all year round. The weather is formed at the bottom of the atmosphere of the Earth, which is called the troposphere, and the next layer - the stratosphere. Approximately a height of 50 km.

Weather types are affected by atmospheric pressure, wind power, its direction, presence or absence of clouds, rain - rain or snow, humidity, fog and many other meteorological processes.

Types of weather

Often the description of the weather is based on its main features. This is the presence of wind, sun, clouds or clouds, precipitation. At any point of the earth's surface, people see almost identical weather changes. Only in warm countries, the precipitates are rain, and in the northern regions - snow. We highlight several types of weather existing on our big planet.

1. Clear weather. For this type, a bright light sky is characterized, without clouds or with a minor amount.

2. Cloud. With such a type of weather, small clarifications are characterized, often accompanied by shrins and thunderstorms.

3. Cloudy. Accompanied by low layered clouds and short-term frosting rains, dampness and fogs.

4. Bad. This type of weather is accompanied by numerous clouds, precipitation, harsh winds with gusts. Winter - blizzard.

What does it mean?

This is basically an anticyclonal weather type. In winter, clear days are occurring after a sharp arrival of the cold and the moderation of the wind strength. Strong frost can be observed in Russia in Siberia, when the air temperature drops to -30 degrees into clear windless days. Air humidity during this period is too small, so precipitation almost does not happen. Dry weather is observed even during cyclones.

In the European part of Russia, this is rarely observed. There are often southern air flows, which carry humidity, strong fogs and low clouds.

In the warm season, clear weather happens in places where very high air temperature. The heat contributes to the fact that the air is deprived of the slightest moisture. Such weather says about Anticyclone. Although in such heat and with humidity up to 30% and in cyclones may not fall out.

Cloudy with clarification

This is the predominant type of weather for the summer warm period. From places with a lower temperature, the cool air enters the area with a well-warmed and warm surface of the Earth. This leads to the formation of convective air flows up. As a result, cumulative and brown clouds are formed, which, gradually gaining power, discharged by shower.

In the clouds after the rain, enlightened areas appear. In Russia, such unstable weather prevails during the warm periods of the year. This type of weather is characteristic of the Lower Volga. There are often livne in spring. Thanks to the plots with enlightenment, it may sometimes rain go only in one area of \u200b\u200bthe city and be the weather is clear in the other.

Frowning weather

This type is characterized by the presence of low layered clouds, frequent frosting rains or snow. This is the predominant type of weather for winter in Russia and throughout Europe. The warm air of the anticyclone from the southern edges is sprinkled along the cold surface and cooled. Due to high humidity, fog and layered clouds are formed, which are located low above the surface of the Earth.

Weak uplink air flows are highly raised, so the vertical power of these clouds is small and covers the lowest edge of the troposphere. Cloudy weather is usually accompanied by morning fogs and drinkers. This zone of blurred atmospheric fronts may be part of the sector of the initial stages of cyclonic perturbations.

Bad weather

Such a cyclone type of weather is characteristic of the zones of both cold and warm fronts. In rainy weather there is an active and numerous cloud formation, abundant sediments both in summer and in winter. Also observed a strong impusty wind. If bad weather happens in winter, then accompanied by snowstorms, snowy drifts. The duration of such a state of the atmosphere continues until the cyclonic atmospheric front is over this area of \u200b\u200bthe earth's surface.

Such types of weather in Russia are found in Western Siberia, as well as in the winter and in the European part, especially the Northern and Central regions. In the south, there are cases of rainy weather extremely rare.

There are many more weather divisions on various types. There is a gradation for air temperature. It is from the extremely hot to the cool in the warm season and from thawed to the extremely frosty in winter.

There are still medical predictions that take into account the influence of weather conditions, atmospheric pressure and wind strength on human well-being and warn people in their forecasts. This is very important, since many people react to change in weather conditions.

Despite the huge selection of Internet sites about the weather, only a few of them use their own forecasts. For example, it is not necessary that the weather on Sinoptik.ua can be clarified by Yandex, as both services, like hundreds of others, use the data of the Finnish Meteorological Service Foreca.

It is also unlikely that there are significant differences in the forecast from British BBC and Russian RP5 . Both services enjoy the data of the British Meteorological BureauMetOffice.

And here are the American giants asWeather Underground, Accuweather, Weather Channel Build their forecasts based on the American numerical prediction model GFS (Global Forecast System).

Strictly speaking, today in the world there are three main global numerical weather forecasting models, or atmospheric hydrodynamic models. That is, data from all meteorological stations of the world, satellites, ships and other systems are analyzed, collected and treated with three main methods based on nonlinear equations.

In the city of Reading in United Kingdom there is an ECMWF model office (European Center for Medium-Range Weather Forecasts). It is this prediction model that Foreca uses one of the world's leading providers of the "weather" content. Today, this model is the newest, quickly develops and gained the fame of the leader with the accuracy of long-term forecasts.

The UKMET model is the brainchild of the oldest meteorological service of the world MetOffice - British government meteoobyuro. It is believed that it is richer than others by scientific potential and gives the most accurate short-term forecast.

As for American GFS, it has the biggest coverage (almost the entire globe) and, according to experts, is the most conservative. The GFS model is operated on by NOAA (National Oceanic and Atmospheric Administration) - US National Center for Atmospheric and Ocean Research. Now the initial GFS data is in open free access on American servers. Nevertheless, experts argue that for our latitudes it is the least adapted, since it does not take into account the snow covers.

The hydrodynamic atmospheric model is a unique, complex and expensive product that exists in a single instance. One run model takes several hours of processor time on a supercomputer. Therefore, for the meteorological service of various countries and commercial organizations, the owners provide access not to the model itself, but to the final results of the calculations: global fields of meteorological values \u200b\u200bon the planet for different heights at different points in time.

In turn, weather services can use their interpolation algorithms and presenting the settlement data of the model. Therefore, differences in weather forecasts arise even where they take the same model as the basis.

Many meteoreracessions combine these major global models and use a variety of additional "wind amendments" from leading world meteorological organizations.

It is quite a unique product of American and Indian programmers with computational facilities in Denmark and Germany.

Professional American Metexite for the most advanced users with its own forecast based on the GFS model coverage over the entire globe. The resource belongs to Weather Services International (WSI), which is part of the Weather Channel group of companies. WSI claims that they own the world's largest commercial meteorological database, collaborating with USA, Canada, Japan and Great Britain. These forecasts enjoy the majority of world airlines, the resource supplies weather content for 60,000 media and energy sector companies.

The non-English-speaking user of the site when looking for weather in his city should not forget to switch from the Fahrenheit scale on Celsius.

In addition, Intellicast specializes in providing information about hurricanes and tornadoes. It is here that most ordinary Americans receive warnings about impending natural disasters.

The Weather Air Force of the Air Force from one of the world's leading news agencies appeared online in 1997 and provides weather information under the license of the British Meteorological Service Metofichce, that is, uses the prognostic model of UKMET. The Meteorological British Bureau is the oldest weather service in the world: it was founded in 1854, and in 1861 introduced the first official weather forecast for English newspapers. Now the forecast is made up for 5,000 cities in the world. What is the most interesting, it is short-term forecasts from the Air Force that are the most accurate for Kiev for reviews on the Internet.

  1. 9. WWW.WEATHER.COM.

The service of the American television channel about the weather The Weather Channel (TWC) is now transoving to a huge corporation. The channel began its broadcast in 1982, and the site opened in 1995. What is noteworthy, the founder of the Canal John Colman is the leading criticism of the theory of global warming. Naturally, Americans use the GFS forecast model. Weather.com replays the search engine Yahoo, and from the features of the resource - various specialized services, for example, forecasts for gardeners with plants care tips. Unfortunately, the data is represented only on the Fahrenheit scale, so the resource is not popular in our latitudes. But for the inhabitants of the Western Hemisphere - this is No. 1.
