How does the meteorological station predict the weather change?

The weather forecast made by the weather station for a certain period in the future is based on the changing trend of temperature, humidity, dew point, air pressure and air mass, using a unique calculation equation, analyzing images from meteorological satellites, and comparing them with the meteorological historical records in the same place at the same time in the past, so as to make a more likely weather forecast.

Meteorology has no national boundaries, and there are many weather stations and observation stations all over China. There is information and data exchange between weather stations and between weather stations and observation stations in neighboring countries.

Example 1: In winter, a cold air mass has formed in Siberia, and it tends to move southward, and there is coordination between meteorological stations in the two places.

Example 2: During typhoon season, a typhoon has formed in the western Pacific Ocean, and it tends to move westward, and there is coordination between stations.

Forecasters generally make "conservative" predictions when the overall large-scale meteorological changes tend to fluctuate and change rapidly, unless they are very sure.

For the probability of precipitation, all weather stations are expressed as a percentage.
