What is the procedure for the National Meteorological Center to "make" weather forecast?

According to my personal thoughts, for reference only:

There are two main parts:

1, numerical forecast correction: now the numerical forecast ability is very strong, accurate enough that each county can directly calculate the forecast results. The National Meteorological Center mainly weighs and applies various numerical forecast conclusions, and corrects them according to the forecaster's experience to find out the weather with the greatest risk impact in the country. In fact, the most important thing is to draw lines, the rain area map of CCTV weather forecast at night, and the cold wave range area. )

2. Step-by-step consultation (weather consultation is to listen to many people's opinions and get a comprehensive forecast idea): The specific conclusion of every accurate weather forecast in the county can only be decided after at least three levels of consultation. At eight o'clock in the morning, the National Bureau guides the Provincial Bureau to discuss the weather, and the Provincial Bureau guides the Municipal Bureau to discuss it during the day. The municipal bureau will discuss it on its own according to local characteristics. The final forecast conclusion is finally determined by the Municipal Meteorological Observatory and reported to the National Bureau on time. (The forecast of weather elements specific to a city, such as weather phenomena, temperature, wind speed and wind direction in Taiyuan, is determined by Taiyuan Meteorological Bureau, but this conclusion is a comprehensive conclusion drawn by the National Bureau, the Provincial Bureau and the Municipal Bureau due to step-by-step consultation. )
