What kind of computer application does weather forecast belong to?

Weather forecast belongs to the application of scientific calculation in computer.

In the past, meteorological departments in some countries and regions used black warning signals to report extreme weather conditions, such as rainstorm, typhoon, high temperature and cold. However, some meteorological departments believe that the black warning signal may cause public panic and anxiety, so they choose not to use it any more.

The warning signals of disastrous weather are divided into eleven categories: typhoon, rainstorm, high temperature, cold wave, fog, thunderstorm and gale, gale, sandstorm, hail, snowstorm and road icing.

Early warning signals are generally divided into four levels. According to the severity and urgency of the disaster, the colors are blue, yellow, orange and red in turn. At the same time, they are marked in Chinese and English, representing ordinary, heavy, serious and particularly serious respectively, and are accompanied by universal disaster prevention guidance.

according to the coverage area, the weather forecast can be divided into: large-scale forecast. Generally speaking, it refers to global forecast, hemispheric forecast, continental or national forecast. Mainly produced by World Meteorological Center, Regional Meteorological Center and National Meteorological Center.

medium range forecast. Often refers to the province (area), state and regional forecasts, made by provincial, municipal or state meteorological stations and regional meteorological stations. Small-scale forecast. Such as the forecast of a county, city, reservoir, airport and port, etc. These forecasts are made by local meteorological stations.

Importance of "early warning" of meteorological information:

It is understood that under the background of global warming, extreme disastrous weather is widespread, frequent, repeated and concurrent. Zhuang Guotai, director of China Meteorological Bureau, said that meteorological warning and forecasting information was sent early.

improving predictability can make meteorological disasters "prevent before they occur, resist at the first time, and save in key links", so as to give priority to prevention, combine prevention with treatment, and prevent before they occur, and effectively play the basic and leading role of meteorological disaster prevention and mitigation.

At present, the early warning information of severe convective weather can be released 4 minutes in advance in China, and the accuracy of rainstorm warning in China reaches 89%, and 152 types of early warning information in China can reach emergency responders within 3 to 8 minutes.

The timely release of early warning information helps crops to "hide" from drought and cold, and also reminds people to pay attention to travel arrangements. The signals of blue, yellow, orange and red are an early warning and a source of security.
