How does the computer weather model predict the weather?

Computer weather model is based on meteorological data from all over the world, including wind direction, wind speed, temperature, humidity, air pressure and so on. The high-altitude meteorological instruments of 650 meteorological balloons in China collect meteorological data, all of which are sent to the working satellites in geostationary orbit, and then sent back from space to the satellite ground receiving station, and then sent from the ground station to the meteorological center. After a few minutes, the information recorded by buoys or airborne acquisition devices in various places will be collected in the center, and many computers will quickly process all kinds of data, thus forming a mathematical description of the weather at that time. The meteorological center in the United States sends 2000 such reports to major forecasting centers every day, and then transmits them to local institutions through them. Local meteorological stations publish local weather forecasts in combination with the latest satellite images, measured data on the ground and their own experience.
