Why is it dry in autumn?

Autumn dryness should first be divided into regions. From autumn to autumn in temperate regions of China, the dry, cold and high pressure in the north gradually moves southward, so the climate is relatively dry. Moreover, due to the confrontation of cold and warm air pressure, the dry weather in autumn usually begins with several rains.

Please remember that the dry climate in autumn in China is related to the air pressure, and has nothing to do with the temperature difference between morning and evening and the dust. Those are just the results of weather changes.

In addition, the northern part of China is called Siberian high and the southern part is called equatorial low.
