Steps to publish weather forecast

The release steps of weather forecast include meteorological observation, data collection, numerical forecast and release of forecast products.

1, 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.

2. Data collection and numerical prediction.

Observers should manually observe the temperature every hour, then compare it with the automatic observation data, and upload the obtained data to China at 2: 00, 5: 00, 8: 00, 1 14: 00, 17: 00, 20: 00 and 23: 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.

3. Forecast product release.

After the conclusion of weather forecast is made, it will be made into different forms of forecast products. Through radio, television, newspapers, internet sites, mobile phone messages, information display screens and other media to the public. This is the weather forecast that everyone watches and listens to.

3. Power system

Weather has a great influence on electricity consumption, so power companies predict electricity consumption through weather forecast.

4. Other private enterprises

Other private enterprises can also adjust demand and supply through weather forecast. For example, supermarkets can provide more drinks in hot weather.
