Snow or rain? Cloudy or clear? Slippery, dry? Will it drip or gush like a bucket? Final chord: "how many degrees above zero?"
The meteorological situation for a modern person is an opportunity to foresee, manage to adjust plans, take care of children, plan out-of-town affairs, and how many things ...
The weather forecast has become an integral part of the plan for the day. Forecasters do not always live up to expectations in terms of reliability. The Internet has become a lifeline for quickly obtaining detailed and general weather conditions around the world.

It is easy to drown in the information flow, often contradictory, predicting meteorological data. There is no shortage of sites. By adhering to certain criteria regarding the source of information, one can successfully maneuver in the ocean of predictions about the behavior of the weather.
Anomalies of nature, the suddenness of events and technological progress, which intervened in the natural course of atmospheric phenomena, reduced the period of a reliable forecast.
The optimal period is considered to be a week period. Some web resources provide information for 90 days ahead, but the errors of such forecasts are large. The longer the period of time coverage, the higher the risk of erroneous information.
The percentage of forecast distortion is directly proportional to the increase in the forecast period.
People who have been listening to forecasts for 3-4 decades have noted the emergence of a new weather parameter - “feels like”. The characteristic changes with the readings "wind speed - air humidity".
Mankind likes to think that some weather forecaster has a special sign, goes out into the open sky and compares his feelings with the given parameters. Alas!
The freezing of water, the speed of the process - and there are the foundations of the wind-cold index. It is fair to say that there is a table, and it determines the ratio of wind speed and the rate of freezing of water.
Stuffiness in the heat determines the humindex index, which links the dependence of humidity on temperature indicators.In this criterion, the dew point is fundamental. The temperature value at which air vapor condenses into a drop on the earth's surface is the stuffiness index. The parameter was put into use in forecasting in mid-1979 in Canada.
The heat is felt the harder, the higher the index mark.
The meteorological services of the 21st century are equipped with computer systems capable of combining not only both indices, displaying the result at the current moment, but also taking into account additional characteristics of the atmosphere.
Such software is the subject of a patent. The world famous weather company AccuWeather, at one time, patented the RealFeel algorithm, which is able to take into account the maximum number of factors in real time.
Detailing parameters is divided into many steps of different characteristics. For example, you can find out what period of time in minutes the sun was clear, and how well it warmed up in degrees.
Residents of megacities often face differences in weather conditions in different parts of the city. The length and area of settlements is so large that the weather sectors have time to change over a single period of time.
Vivid manifestations of differences occur both in off-season periods and during thunderstorms, hurricanes, and snowfalls. The natural phenomenon passes by a "narrow front". Once in the city under heavy rain and arrived in a holiday village, you can find dry roads.
It is recommended to customize the application search or search for weather information, localizing the location as much as possible.
Cooperation with military meteorological services and airport weather stations gives additional advantages to forecasts in terms of reliability. The degree of responsibility of official structures is much higher, therefore the quality of the information provided differs from the average consumer.
For permanent use, take the time to study the provided weather data from multiple sites.
The following points need to be analyzed for the correct decision:
There are several convenient ways to instantly receive an atmospheric summary from the site:
These methods save charging and time resources.
Meteorological expected indicators are classified by timing.
Forecast type name | Period, hour, day + characteristics |
---|---|
Current | Up to 2 hours |
Super short term data | 12 hours |
Short-term characteristics of the forecast | 3 nights |
Medium-term forecasts | from 3 days to 10 days |
Extended. With average values | 10-30 days, with possible deviations from accepted norms |
Long term expected atmospheric conditions | from 30 days to 2 years |
Approximately expected for a month | possible deviations from the average values |
Projected 3 months | averaged data with predicted deviations |
Seasonal forecasts | for seasonal averages |
climatic | waiting time exceeding 2 years |
Climatic variability | impact of changes on expected parameters |
Climate change | taking into account anthropology |
Nowcasting - Short-term forecast for the period from 2 to 6 next hours.In addition to extrapolating daily trends, remote sensing is used. It can be satellite and radar data options. A new step in nowcasting was the use of atmospheric numerical models.
The classification takes into account standard seasonal indicators, deviations from the norms, and the influence of external factors.
An important factor in forecasting is automatic adjustment. Special innovative technologies, artificial intelligence systems give great advantages to the owner companies.

Animated interesting site is presented in the form of a map of the whole world with accessible detail, in a mobile application it is especially good in terms of information content.
There are about 2,000 meteorological stations in Russia, over 55,000 in China, and hundreds of thousands all over the world.Not all synoptic services are serviced by specialists, there is a network of ASOS, automated observation systems.
1,000 US airports have automated weather forecasting and tracking systems.
Weather buoys are located on the surface of the world's water bodies, which measure temperature indicators, barometric indicators, and wind directions.
Weather radars with a high frequency of area coverage can provide very accurate weather reports in the short term.
At the service of predicting atmospheric and natural phenomena are also low-orbit satellite systems. Thanks to satellites, three-dimensional maps are created with characteristics of the properties of clouds, temperatures, water vapor.
Every second there is a tireless work on the collection and exchange of data, streams of parameters flow into specialized meteorological information processing centers equipped with powerful computer systems that work with the introduction of innovative technologies.
Statistical and mathematical models complement a huge block of information for weather reports.
Is it worth it to be upset if, at times, weather forecasters are mistaken, because going outside in any weather is, in itself, already happiness!
