How does CCTV news release the secret video of weather forecast, and how is it made?

The weather forecast is mainly completed through the following three steps: the collection of meteorological data, the analysis and calculation of meteorological data, the consultation of forecasters, the conclusion of the forecast and the release. The collection of meteorological data sounds simple, but if it is really implemented, it is really not easy. From flat ground to thousands of feet of sky, from boundless land to vast ocean, every step is troublesome. After the computer collects relevant data, it processes and calculates the data to obtain weather charts, numerical forecast charts and other products, and sends these conclusions to local forecast stations through networks, satellites and other channels to provide forecasting basis for forecasters. No matter weather forecast method, numerical forecast method or other forecast methods, there are certain limitations. Forecasters of meteorological stations need to comprehensively judge and analyze the forecast results, negotiate with each other, and finally reach a consistent conclusion through discussion.
