How is the weather forecast released?

The first step is to collect raw materials. There are two kinds of raw materials, one is the actual monitoring data, and the other is the numerical forecast product. The actual monitoring data comes from various monitoring equipment and means such as high altitude, ground observation, satellite cloud picture, weather radar echo and lightning location. In China and the world. Knowing the actual situation of the current atmosphere through various monitoring data is the premise of making weather forecast, so forecasters can know the location and intensity of cold and warm air and the weather it produces, such as whether there is precipitation, temperature, wind direction and wind speed. Experienced forecasters can infer the future weather through live scenes. The product of numerical forecast comes from numerical model, which is a quantitative and objective forecast made by large computers by solving the equations of fluid mechanics and thermodynamics describing the weather evolution process through numerical calculation. The numerical model gives the future state of air pressure, temperature, wind and humidity. Only by mastering the future atmospheric motion state can we predict the future weather changes. The second step is to analyze raw materials and make weather forecast. Forecasters use the principles of meteorology, dynamics, thermodynamics, etc., comprehensively analyze the live data and numerical forecast products, and make weather forecasts in the next 3 or 7 days. Of course, for the same meteorological data, different forecasters will give different forecast conclusions, so after consultation and discussion, a weather forecast conclusion of the day is finally given. The third step is to release the forecast products. After the forecaster makes the weather forecast conclusion, it can be released to the public. (Zonghe)
