The weather forecast is only a forecast, and the weather is affected by various factors. In fact, weather forecast needs many scientific theories and methods to make. It is an applied science, and even a little purer can be regarded as applied mathematics. In fact, weather forecast needs many scientific theories and methods to make. The initial forecasting method was basically based on empirical statistics (statistical forecasting is still used now, basically used in climate forecasting). Modern weather forecast is basically based on numerical forecast, combined with satellite data, radar data, weather map and real-time observation data for comprehensive forecast.

Weather forecast (measurement) or meteorological forecast (measurement) is to use modern science and technology to predict the state of the earth's atmosphere in a certain place in the future. Since prehistoric times, human beings have begun to predict the weather and arrange their work and life accordingly (such as agricultural production and military operations). Today's weather forecast mainly uses the collection of a large number of data (temperature, humidity, wind direction and speed, air pressure, etc. ), and then use the current 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.
