Weather forecast (measurement) or meteorological forecast (measurement) is to predict the state of the earth's atmosphere in a certain place in the future by using modern science and technology, which mainly includes rain, snow, maximum and minimum temperatures, wind direction and wind force and special disastrous weather in a certain area or city in the future. Since prehistoric times, human beings began to predict the weather to arrange their work and life accordingly (such as agricultural production, military operations, etc.). ).

The satellite cloud image of China Central Meteorological Observatory was taken from Fengyun-1 and other meteorological satellites. Using satellite cloud images for analysis can improve the accuracy of weather forecast.

From the17th century, scientists began to use scientific instruments (such as barometer) to measure weather conditions and use these data to make weather forecasts. But for a long time, people can only use local meteorological data to make weather forecast, because at that time, people can't transmit the data to a distant place quickly. 1837 after the invention of the telegraph, people were able to make use of large-scale meteorological data for weather forecast.
