Abstract:
The main characteristics of the atmospheric circulation in June 2022 are as follows. The polar vortex with multi centers in the Northern Hemisphere was weaker than normal, the 500 hPa geopotential height field over the Ural Mountains was significantly weaker than normal, and the position of the Western Pacific subtropical high was close to normal moving northward in the last ten days of June. The average precipitation across China in June was 112.0 mm, 9.1% more than the climatology. Shandong, Jilin and Liaoning provinces recorded the most precipitation in the same period since 1961 and Fujian Province also recorded its second most precipitation. The national average temperature in China was 21.3℃, which was 0.9℃ higher than the climatology and also highest record since 1961. There were six regional torrential rain events in this month, mainly concentrated in South China in the first and second dekads, and then moved northward orderly to Sichuan Basin, Huang-Huai Region and Northeast China in the last dekad. There was one typhoon generated in June, which was weaker than normal. In the middle and late June, thunderstorms, gales, hail and short-time severe precipitation occurred in several provinces in northern China, causing heavy damages to local areas. In the early and middle of June, persistent high temperature caught the eastern part of Northwest China, Huang-Huai Region, and southern North China, with high temperature days in some regions exceeding 10 days. The daily maximum temperature at 33 stations broke its highest temperature record.
