In the weather forecast, the temperature is directly expressed by numbers, and the high temperature is generally above 30 degrees Celsius, as shown in the following figure.

Weather forecast is to predict the weather conditions in a certain period in the future by applying the law of atmospheric change and according to the current and recent weather situation. 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 images of China Central Meteorological Observatory are taken from meteorological satellites such as Fengyun-1. Using satellite cloud images 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 (10 ~ 15 days or more). CCTV mainly broadcasts short-term weather forecast every day.
