What kind of wind direction will there be in different seasons? How will the weather change if the wind direction is different?

Most areas in China have a monsoon climate. The southeast wind blows mostly in summer and the northwest wind blows mostly in winter. Spring and autumn are seasons where the monsoons alternate, so the wind directions also alternate.

Generally speaking, when the southeast wind blows, the temperature rises, the air humidity increases, and there are more rainy weather; when the northwest wind blows, the temperature drops, the air is dry, the humidity is low, and there are less rainy weather.

In addition, heavy rainfall often occurs in areas where the summer monsoon (southeast wind) and winter monsoon (northwest wind) meet.
