On what basis does the Meteorological Bureau make rainfall forecast?

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 data such as temperature, pressure, wind direction and wind speed measured by meteorological stations all over the country, and judged by relevant information and experience. This prediction has always been made manually, which is slow and inaccurate. No wonder some people.

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.
