How to generate weather forecast?

First, put some anemometers and anemometers in the high and empty places; Measuring instruments for measuring the highest and lowest temperatures; A rain gauge for measuring rainfall; We also need to analyze satellite cloud images.

Then collect data, process data, integrate data and make weather forecast map.

Finally, it will be reported to various media.

Ps: The weather forecast of CCTV is also the information obtained by weather stations in various urban areas ~ ~

At present, weather forecasting mainly adopts synoptic forecasting method, statistical forecasting method and dynamic forecasting method, and the weather-statistical forecasting method, dynamic statistical forecasting method and weather-dynamic forecasting method formed by combining these three basic forecasting methods.

1. Weather forecast method (or weather map method): it is a method of making weather forecast with weather map as the main tool and using satellite cloud pictures and radar maps. Analyze and study the changing law of weather with the principle of meteorology. This method is mainly used for short-term forecasting.

2. Numerical forecast method (also called dynamic forecast method): it is a method of making weather forecast by solving dynamic equations describing atmospheric motion with a large-scale fast computer. This method can be used for both short-term and medium-and long-term forecasting. In recent years, it has also been used for climate prediction.

3. Statistical forecasting method: it is a method to find out the statistical law of weather changes by using a large number of long-term meteorological observation data, establish a statistical model of weather changes according to the principle of probability statistics, and make weather forecasts. This method is mainly used for medium and long-term forecasting and meteorological element forecasting.
