Meiyu refers to a period of continuous rainy weather from mid-June to early summer in mid-July, from the middle and lower reaches of the Yangtze River in China to 28°-34° N east of Yichang, or the Jianghuai Valley, to a narrow area in southern Japan.

Meiyu formation conditions:

1. There is blocking high pressure or stable high pressure ridge in the middle troposphere in high latitudes of Asia, and the atmospheric circulation is relatively stable with little change. 2. The westerly circulation in the mid-latitude area is gentle, and frequent short-wave activities provide cold air conditions for the Jianghuai area.

3. The western Pacific subtropical high has an obvious process of extending westward and jumping northward. The ridge line of the 500 HPA subtropical high is stable between 20 and 25 degrees north latitude, and the warm and humid air flow is transported from the edge of the subtropical high to the Jianghuai basin. Under this circulation condition, Meiyu front lingers in the Jianghuai basin, often accompanied by southwest vortex and shear line. On the Meiyu front, the mesoscale system is active and the rainfall is abundant.
