How does the simulation system predict weather?

The simulation system uses a radar beam to continuously measure wind direction and wind speed within a range of 1.6 to 14.4 kilometers, and takes wind speed and direction data every 100 meters in the vertical direction, which can be collected for every square kilometer. to hundreds of data. Displayed on the monitor screen: some colorful arrows, with color, length and direction, representing the altitude, wind speed and wind direction respectively. The computer quickly compared the data input a few hours ago with satellite data, and displayed the movement of local airflow on the screen, improving the accuracy of forecasting local microclimate to an unprecedented level.

The computer weather model based in Maryland is based on weather data transmitted from around the world, including wind direction, wind speed, temperature, humidity, air pressure, etc. Meteorological data are collected from the high-altitude weather 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 U.S. weather center sends 2,000 such reports every day to major forecast centers, which then transmit them to local agencies. Meteorological stations in various places combine the latest satellite images and ground measurement data with their own experience to issue local weather forecasts. This forecast has been quite accurate.
