When is the rainy season?

Meiyu season: June and July every year.

Meiyu season is a warm and humid air flow in the Pacific Ocean brought by the southeast monsoon in June and July every year, which passes through the middle and lower reaches of the Yangtze River in China, Taiwan Province Province, south-central Japan and south Korea. Because it is now the mature period of plums in Jiangnan, it is called Meiyu season.

The middle and lower reaches of the Yangtze River in China refers to a period of continuous rainy weather in the range of 28°-34° N east of Yichang or in the narrow area from Jianghuai Valley to southern Japan.

In fact, the criteria for entering Mei are complicated, but generally speaking, there are large rainfall areas in the middle and lower reaches of the Yangtze River and South China. There is a subtropical high near 20 degrees north latitude in the south to prevent the rain area from going south, causing the rain area to wander back and forth in the middle and lower reaches of the Yangtze River, resulting in long-term heavy rainfall. The weather situation has such characteristics that it can almost be considered as "entering the plum blossom".
