Is the weather forecast system a real-time system?

The weather forecast system is not a real-time system. According to relevant public information, the weather forecast refers to the future weather, not the real-time weather. It is a future weather forecast obtained by the professional forecaster of the Meteorological Bureau based on the altitude map and the ground map (that is, meteorological data) and calculated and analyzed by the meteorological satellite data through the supercomputer. As time goes on, the weather forecast is also revised and updated at any time. According to the change of weather, the weather forecast is also changing, and updating the weather forecast will serve the public more accurately.
