How does the weather bureau predict the weather? Who can help me answer? thank you

With the development of science and technology, there are more and more meteorological instruments and stations all over the country. Now the weather forecast is no longer empirical. It is based on the cloud image sent back by Fengyun-1 meteorological satellite and the meteorological map drawn by the data of temperature, air pressure, wind direction and wind speed measured by various meteorological stations, and is obtained through relevant data and experience judgment. This prediction has always been made manually, which is slow and not very accurate. No wonder some people say that the weather forecast is for reference only, and you can't believe it all.

In order to accurately forecast the weather, the data obtained above must be listed into hundreds or even higher order linear equations. If it is solved manually, it will take hundreds of people several weeks to complete. This is not a weather forecast, but a weather report. Now that there are electronic computers, the work is done by computers. It only takes a few minutes to finish this task.

The daily weather forecast of CCTV is calculated by the National Meteorological Administration with two large computers.
