How does the weather forecast measure the weather

Of course, people measured it with professional equipment and technology: "The first is to establish a meteorological observatory. The more weather stations there are, the more accurate the forecast will be. To this end, thousands of weather stations have been established around the world, equipped with various weather radars, and several weather satellites have been deployed in space, forming a global atmospheric monitoring network. This monitoring network observes the atmospheric changes from the ground to the sky and from the land to the ocean at the same time every day in an all-round and multi-level way, and quickly collects the observation data to national meteorological centers and forwards them to all parts of the world.

There are many methods of weather forecast, and there are two most commonly used. One is the traditional synoptic method, that is, the meteorological data at the same time and at the same level are drawn on a special map, and various meteorological elements on the weather map are analyzed, so as to make weather forecasts in various places. The other is the numerical forecast method, and the weather forecast it makes is "calculated" by computer. Because the motion of the atmosphere follows some known physical laws, according to these laws, the motion state of the atmosphere can be written as a set of equations. As long as the initial value is given, the variable values of the time-varying equations can be solved, and the future state of the atmosphere can be obtained accordingly.
