Today's weather forecast is mainly based on the collection of a large number of data (temperature, humidity, wind direction and speed, air pressure, etc.). ), and then use the understanding of atmospheric processes (meteorology) to determine future air changes. Because of the chaos of the atmospheric process and the fact that science has not fully understood the atmospheric process today, there will always be some errors in the weather forecast.
