May 2 1: cloudy to cloudy in northern Zhejiang; There are showers or thunderstorms in other areas, some moderate to heavy rain and some heavy rain.

The reason for the heavy rainfall this round.

According to the statistics of meteorological department, from May 1 1 day to May 18, the number of rainy days in Hangzhou, Huzhou, Jiaxing, Ningbo, Jinhua, Shaoxing and Quzhou in Zhejiang was the highest in the same period in history. The precipitation in Zhejiang province is more than normal, and the rainfall in Lishui and Wenzhou is twice as high as normal.

Experts said that the main reason for this round of rainfall is that the intensity of the western Pacific subtropical high in May1/KLOC-0 was significantly stronger than that in the same period in history, and its location was northward compared with the same period in history; 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 north of Jiangnan. 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.
