Where is the rainy season in China?

Other provinces also have rainy season, but it is not obvious. The typical rainy season mainly occurs in the middle and lower reaches of the Yangtze River in China, starting from Huanghuai area in the north, reaching the central and northern parts of Hunan, Jiangxi and Zhejiang provinces in the south, Yichang in Hubei province in the west and Shanghai in the east. The middle and lower reaches of the Yangtze River in China are usually rainy from mid-June to early July every year.

In the past few days, the sky has been gloomy and the precipitation has been constant, sometimes big and sometimes small. Therefore, there is a popular proverb in southern China: "Rain hits Huangmei's head and there is no sun for forty-five days." Continuous rain, high temperature and high humidity are the main characteristics of plum rain.

The reasons for this are:

The east coast of the mainland is controlled by the west side of subtropical high in summer, and the downward flow is dry, but it absorbs a lot of water vapor from the warm and humid sea surface, bringing abundant precipitation and producing a subtropical humid climate. Due to the strong contrast between land and sea, a unique monsoon climate has formed here, which is characterized by rainy summer and dry winter, with rainfall concentrated in summer, which is just the opposite of the Mediterranean climate.

If compared with the east coast of the United States at the same latitude, it is also a world of difference. There will be no rainy weather for a long time before and after the summer monsoon in the mid-latitude zone of the east coast of the United States, and people do not feel the feeling of sultry weather for a long time, so it is difficult to appear moldy.

It can be seen that the precipitation season at the same latitude varies greatly. So there are only Huangmei in the middle and lower reaches of the Yangtze River in China, starting from the area east of Yichang and 29-33 degrees north latitude, as well as the southeast of Japan and the southernmost tip of the Korean Peninsula.
