Abstract:
The main characteristics of the general circulation of atmosphere in June 2024 are as follows. There were four polar vortex centers in the Northern Hemisphere. The circulation of the mid-high latitude westerlies was distributed in the pattern of four upper-level troughs and four ridges of high pressure, and the position of frontal zone was generally by north. The western Pacific subtropical high was obviously stronger, located more westward than normal during this month. The monthly mean temperature of China was 0.6℃ higher than the normal June temperature (20.4℃). During this month, four high temperature processes were experienced in Northwest China, North China and the Yellow River and Huaihe River regions. With the outbreak of the Indian monsoon and the middle and lower reaches of the Yangtze River into the Meiyu season on 17 June, the monthly average precipitation of China was more than the usual precipitation 102.8 mm by 11.9%. Totally, five regional torrential rain events occurred in most parts of southern China, especially in the south regions of the Yangtze River and Huaihe River where the accumulated precipitation was more excessive clearly. In addition, precipitation in some regions broke the record of extreme precipitation for the same period.
