Why is it always windy in spring, and the south wind and the north wind alternate? What's the impact? Please explain to the prawns. Thank you.

This is the characteristic of the monsoon region in eastern China.

In spring and summer, the center of high pressure is in the Hawaiian Islands in the Pacific Ocean. The wind blows from the high pressure to the low pressure area, so at this time, the summer monsoon from the ocean prevails in China, that is, the southeast wind.

In autumn and winter, the center of high pressure is located in Mongolia and Siberia in Eurasia, so the winter wind, that is, the northwest wind, prevails in China.

If it is in North China, there are many reasons, such as strong wind in spring, rapid land warming in spring, frequent cold air activities and less precipitation.
