How is the weather forecast made?

The first is to collect meteorological data, observe the atmospheric changes from the ground to the sky and from the land to the ocean in an all-round and multi-level way, and collect the observation data quickly. Secondly, the computer processes and calculates the collected data to obtain weather charts, numerical forecast charts and other products, which provide forecasting basis for forecasters. Third, professionals analyze the data and make preliminary predictions. There are many ways to forecast the weather. There are two most commonly used methods. One is the traditional synoptic method, which analyzes various meteorological elements on the weather map and makes weather forecast. The other is numerical prediction method, which is "calculated" by computer. Because the motion of the atmosphere follows some known physical laws, the motion state of the atmosphere can be written as a set of partial differential equations. Given the initial value (the current state of the atmosphere), the variable values of the equations that change with time can be solved. Based on this, the future atmospheric conditions are obtained. Fourth, the final conclusion. Both synoptic methods and numerical prediction methods have certain limitations, and the prediction conclusions are not the same.
