Weather forecast (measurement) or meteorological forecast (measurement) is the use of modern science and technology to pre dict the state of the earth's atmosphere at a certain location in the future. pre dict. Since pre historic times, humans have begun to pre dict the weather to arrange their work and life accordingly (such as agricultural production, military operations, etc.). Today's weather forecasting is primarily based on collecting large amounts of data (temperature, humidity, wind direction and speed, pre ssure, etc.) and then using current knowledge of atmospheric processes (meteorology) to determine future air changes. Because of the chaos of atmospheric processes and because today's science does not finally have a thorough understanding of atmospheric processes, weather forecasts will always have a certain amount of error.

The satellite cloud images of my country's Central Meteorological Observatory are taken from meteorological satellites such as "Fengyun-1". Using satellite cloud images and photos for analysis can improve the accuracy of weather forecasts. Weather forecasts are usually divided into three types based on the length of time: short-term weather forecast (2 to 3 days), medium-term weather forecast (4 to 9 days), and long-term weather forecast (more than 10 to 15 days). CCTV broadcasts mainly short-term weather forecasts every day.
