How to make use of the weather?

After receiving the weather situation report, we can use a national map to record the intensity and location of each weather system on the map, and then record the same weather system on this map the next time we listen to the weather forecast, so that we can calculate the direction, speed and intensity changes of the weather system moving in a certain interval from this map. According to this change law, we can roughly calculate the weather system that will control the local area in the future, and we can also roughly predict the weather in this area. So it is necessary to broadcast the weather in the weather forecast.

Because the weather system has such a moving law, if you want to make a more correct weather forecast, you should not only master the local meteorological data, but also master the distribution of large-scale weather systems and their strengthening, weakening and moving.

Practice has proved that all weather systems are not static, and they all tend to move in a certain direction. For example, high voltage generally moves from Mongolia to China and then to Japan; Low pressure moves from west to east; Typhoons often occur in the Pacific Ocean. Once formed, it will generally move to the west or northwest. When approaching Taiwan Province Province in China, some turned northeast and moved to Japan, some continued to move westward into the South China Sea, some continued to move inland after landing on the southeast coast of China, or turned northeast and went out to sea again and moved to Japan.
