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 methods of weather forecast, and there are two most commonly used.
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 can be solved over time, and the future state of the atmosphere can be obtained. Fourth, the final conclusion. Both synoptic methods and numerical prediction methods have certain limitations, and the prediction conclusions are different.
