Causes of recent heavy rainfall in South China

From May 1 1, the intensity of the western Pacific subtropical high is obviously stronger than that of the historical period, and its position is northward compared with the historical period. The southwest monsoon is strong and has been maintained, and a large amount of water vapor is transported from the South China Sea to the intersection of cold and warm air currents.

The above factors led to the rain belt originally located in South China being pushed to the northern part of Jiangnan at this time. Although the rain belt swings from north to south, Zhejiang is disturbed by the rain belt most of the time, so the rain keeps coming.
