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, but how many things ...
The weather forecast has become an integral part of the day's plan. Forecasters do not always meet expectations in terms of reliability. The Internet has become a lifeline for promptly obtaining detailed and general weather conditions around the world.

It is easy to drown in an often contradictory information flow predicting meteorological data. There is no shortage of sites. Adhering to certain criteria regarding the source of information, you can successfully maneuver in the ocean of predictions about the behavior of the weather.
Natural anomalies, suddenness of events and technical progress that intervened in the natural course of atmospheric phenomena have shortened the period of a reliable forecast.
The optimal period is considered to be a weekly period. Some web resources provide information for 90 days ahead, but the errors of such forecasts are large. The longer the time span, the higher the risk of misinformation.
The percentage of forecast bias is directly proportional to the increase in the prediction period.
People who have been listening to forecasts for 3-4 decades have noted the appearance of a new weather parameter - “it feels like”. The characteristic changes with the readings "wind speed - air humidity".
Humanity is pleased to think that a certain weather forecaster has a special sign, goes under the open sky and compares his feelings with the given parameters. Alas!
Freezing of water, the speed of the process - these are the basics of the wind-cold index. It is fair to say that there is a table, and it determines the ratio of wind speed and water freezing speed.
The stuffiness in the heat determines the humindex index, which relates the dependence of humidity on temperature indicators. In this criterion, the dew point is fundamental. The temperature value at which the condensation of air vapor into a drop on the earth's surface occurred is the stuffiness index. The parameter was introduced for forecasting in mid-1979 in Canada.
The heat is felt the heavier, the higher the index mark.
The equipment of the 21st century meteorological services is 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 meteorological company AccuWeather, at one time, patented the RealFeel algorithm, which is able to take into account the maximum number of factors in real time.
Parameter detailing is broken down into many steps of various 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 metropolitan areas often face differences in weather conditions in different areas of the city. The length and area of settlements is so great that the weather sectors have time to change in a given period of time.
Vivid manifestations of differences occur both in off-season periods and during moments of thunderstorms, hurricanes, and snowfalls. A natural phenomenon passes by a "narrow front". Once in the city under the pouring rain and after arriving in a summer cottage village, you can find dry roads.
It is recommended to customize the search for the application or search for information on the weather, localizing the location as much as possible.
Cooperation with military meteorological services and airport meteorological stations provides additional advantages in terms of reliability of forecasts. The degree of responsibility of the official structures is much higher, therefore the quality of the information provided differs from the average consumer.
To use it on an ongoing basis, you should take the time to study the weather data provided from multiple sites.
To analyze for the correct decision, the following points are necessary:
There are several convenient ways to instantly get an atmospheric summary from the site:
These methods save chargers and time resources.
The meteorological expected values are classified by timing.
Forecast type name | Period, hour, day + characteristics |
---|---|
Current | Up to 2 hours |
Super short term data | 12 hours |
Short-term forecast characteristics | 3 days |
Medium-term forecasts | from 3 days to 10 days |
Extended. With averaged values | 10-30 days, with possible deviations from the accepted norms |
Long term expected atmospheric conditions | from 30 days to 2 years |
Estimated for a month | possible deviations from the average |
Projected 3 months | averaged data with predicted deviations |
Seasonal forecasts | for seasonal averaged data |
Climatic | expectations exceeding 2 years |
Climatic variability | impact of changes on expected parameters |
Climate change | considering anthropology |
Sciencecasting - Short-term forecast for the period from 2 to 6 next hours. In addition to extrapolating daily trends, remote sensing is used. These can be satellite and radar data options. A new step in naukasting was the use of atmospheric numerical models.
The classification takes into account the standard seasonal indicators, deviations from the norms, the influence of external factors.
Automatic correction is an important factor in forecasting. Special innovative technologies, artificial intelligence systems give great advantages to the companies-owners.

A popular weather site with a user-friendly interface covers the weather up to regional centers in the regions.
The resource has the entire set of characteristics:
Maps are presented by 4 parameters - precipitation, wind, cloudiness and temperature conditions for the next 5 days.
Informational and understandable version of the forecast site.
The user is offered a console of several blocks:
The site uses Meteum technology for accurate forecasts.

The US resource covers 3 million locations of the world population. The history of the site goes back to 1965, when the targets of the forecasts were media and TV platforms. 1995 switched the resource to commercial rails, and at the moment Accu Weather is a meteorological business service that aims to create a forecast product for mobile applications and PC software.

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