Summer in the south is full of disasters. Why is it always rainy and rainy in the south?

Because the south, especially the southeast coastal area, belongs to subtropical monsoon humid climate, it is hot and rainy in summer, so the frequency of rain is relatively high, especially in rainy season, and the climate is more frequent and changeable. Cities near the southeast coast are also affected by the Pacific ocean monsoon, so rainfall is also a very common phenomenon.

Summer is coming soon. I believe everyone has watched the news these days. Now the southern region has entered the flood season and rainy season, while the number of rainy days in the north is relatively small. Many people are curious. Why does it often rain in the south? This is related to the climate in the south. First of all, most areas in the south belong to subtropical monsoon climate, such as Zhejiang and Jiangxi, and the southeast coast such as Guangdong and Fujian. Because it is close to the sea, it is affected by the ocean monsoon. It is often hot and rainy in summer, and the relative humidity in the north is small, which belongs to semi-humid and semi-arid areas.

Most provinces in the south are located in the monsoon climate zone, so the cold current and warm current often meet here, and the air mass blown from the Pacific Ocean also contains a lot of water, so once it meets the cold current air mass, it will land in the form of rain, which is why it often rains in the south. Cities near the sea, because the ocean also releases a lot of water vapor, are said to be very humid in summer in the southeast. For example, the summer precipitation in Fujian and Guangdong ranks among the top in the country.

Southern Jiangsu, Zhejiang, Shanghai and other Yangtze River Delta regions have entered the rainy season in early summer, that is, Huangmeitian. The rainy season is also a unique weather phenomenon in East Asia. It is not only easy to appear along the Yangtze River in China, but also often occurs in Japan and southern Korea. There is continuous rainfall in the rainy season, and it may be sunny for a while, and then the weather will change. This phenomenon is normal, and
