Meteorological disaster early warning signal (hereinafter referred to as early warning signal) refers to the early warning information released to the public by meteorological offices and stations affiliated to competent meteorological departments at all levels. Early warning signals are composed of names, icons, standards and defense guidelines, which are divided into typhoon, rainstorm, blizzard, cold wave, gale, sandstorm, high temperature, drought, lightning, hail, frost, fog, haze, road icing and so on.

The meteorological disaster warning signals are generally divided into four grades (IV, III, II and I), which respectively represent ordinary, heavy, serious and particularly serious, and are marked in Chinese and English, which are consistent with all emergency treatment grades and colors of the country.

Weather forecast (measurement) or meteorological forecast (measurement) is to use modern science and technology to predict the state of the earth's atmosphere at 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, military operations, etc.). Today's weather forecast mainly uses collecting a large number of data (temperature, humidity, wind direction and speed, air pressure, etc.), and then uses the current understanding of atmospheric processes (meteorology) to determine future air changes. Because of the chaos of atmospheric process and the fact that science has not finally understood the atmospheric process thoroughly today, there is always some error in weather forecast. [1]?

The satellite cloud images of the Central Meteorological Observatory in China were taken from meteorological satellites such as Fengyun-1. Using satellite cloud photos for analysis can improve the accuracy of weather forecast. Weather forecast is usually divided into three types: short-term weather forecast (2 ~ 3 days), medium-term weather forecast (4 ~ 9 days) and long-term weather forecast (more than 1 ~ 15 days). CCTV broadcasts mainly short-term weather forecasts every day.
