The process of making weather forecast

The production process of weather forecast is as follows:

Meteorological observation, meteorological observation provides the most basic data for weather forecast. At present, China has initially established space-based, ground-based and space-based meteorological stereoscopic observation systems. The sunshine meter measures the sunshine time every day. Geothermal meters are divided into deep geothermal meters, shallow geothermal meters and surface thermometers. Rainfall pipes are used to measure rainfall, frozen soil devices are used to measure frozen soil depth, and automatic anemometers are used to measure wind speed and direction. After the release of forecast products and the end of weather forecast, they are made into different forms of forecast products. Through radio, television and newspapers.

For data collection and numerical forecast, the observer should observe the temperature manually once every hour, and then compare it with the automatic observation data, and obtain the data at 2: 00, 5: 00, 8: 00, 1 14: 00, 17: 00, 20: 00 and 20: 00 every day. China Meteorological Bureau made these data into cloud images and sent them to meteorological departments all over the country, and then made them public to the whole world.

Brief introduction of weather forecast:

Weather forecast, also known as weather forecast, refers to the use of modern science and technology to predict the state of the earth's atmosphere in a certain place in the future. Since prehistoric times, human beings have begun to predict the weather to arrange their work and life. Today's weather forecast is mainly through collecting a large number of data, and then using the understanding of atmospheric processes to determine the future air changes.

The satellite cloud images of China Central Meteorological Observatory were taken by Fengyun-1 and other meteorological satellites. 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, medium-term weather forecast and long-term weather forecast.
