How does the meteorological station predict the temperature?

Simply put, it is to design a huge program to calculate the weather forecast, and input the currently known weather phenomena, so that it can calculate the future atmospheric motion state and weather conditions. Numerical weather forecast is the basis of modern weather forecast.

The change of weather is the result of the change of atmospheric movement around the earth. The basic laws of fluid mechanics and thermodynamics in physics can be used to analyze the movement and change of the atmosphere, and these laws can be written into mathematical equations in mathematical language. Then, people use large computers to solve these mathematical equations, and then predict the future air pressure, temperature, wind direction, wind speed and precipitation in a certain area. ...

At present, any forecasting model can't simulate the atmospheric evolution completely and truly, and it can only be approximate, so there must be errors. Moreover, the error will accumulate, and the longer the prediction time, the greater the error.

Because of this, the numerical forecast needs manual correction. The 7-day forecast published by China Weather Network is revised by meteorological experts at all levels according to the results of model forecast, combined with current observation data, local climate characteristics, topography and personal forecasting experience, and then released to the outside world.
