How do computer weather models predict weather?

Computer weather models are based on meteorological data transmitted from all over the world, including wind direction, wind speed, temperature, humidity, air pressure, etc. Meteorological data are collected from the high-altitude climatology instruments of 650 weather balloons across the country, and are all sent to working satellites in geostationary orbit, and then sent back to the satellite ground receiving station from space, and then sent to the meteorological center from the ground station. The information recorded by buoys or airborne collection devices in various places is gathered in the center within a few minutes, and many computers quickly process various data to form a mathematical description of the weather situation at that time. The weather center in the United States sends 2,000 such reports every day to major forecast centers, which then transmit them to local agencies. Meteorological observatories in various places combine the latest satellite images and ground measurement data with their own experience to issue local weather forecasts.
