What are the five processes of making weather forecast?

The five processes of making weather forecast are as follows:

1, data acquisition.

2. Digital weather forecast.

The weatherman made a forecast.

4. Weather consultation.

5. Publish the weather forecast.

Specific process:

1. Data collection: The most traditional data are data such as air pressure, temperature, wind speed, wind direction and humidity collected by professionals, amateurs, automatic weather stations or buoys on the ground or at sea. The World Meteorological Organization coordinates the timing of these data collections and sets standards. These measurements are made every hour (METAR) or every six hours (SYNOP).

2. Data assimilation: In the process of data assimilation, the collected data are combined with the digital model used for forecasting to produce meteorological analysis. The best estimate of its atmospheric state is the three-dimensional representation of temperature, humidity, air pressure, wind speed and wind direction.

3. Data Weather: According to the results of physics and fluid mechanics, calculate the changes of the atmosphere with time.

4. Output processing: The original output calculated by the general model must be processed before it can become a weather forecast. These treatments include using statistical principles to eliminate the deviation in known models or making adjustments with reference to the calculation results of other models.

5. Production process: according to the data provided by relevant departments, the national meteorological situation map is produced on the computer; The host stood in front of a blue screen and pointed to explain the weather; The film and television center synthesizes images and uses charts instead of blue screens on the computer; The film and television center transmits the completed program to CCTV.
