It is based on the analysis of satellite cloud images and weather maps, combined with the comprehensive study of meteorological data, terrain and seasonal characteristics, and mass experience. For example, the satellite cloud image of China Central Meteorological Observatory was taken by Fengyun-1 meteorological satellite made in China. Using satellite cloud images for analysis can improve the accuracy of weather forecast.
