Analysis of the March 2025 Atmospheric Circulation and Weather
摘要
Abstract
The main characteristics of the general atmospheric circulation in March 2025 are as follows:The Northern Hemisphere polar vortex exhibited a multi-type distribution with enhanced intensity.The mid-high latitude circulation presented a four-wave pattern,while the Asian circulation remained relatively zonal.The southern branch trough was stronger than normal.The national average temperature was 5.3℃,0.5℃ higher than that in the same period of years.The national average precipitation was 28.3 mm,3.7％lower than normal overall.The precipitation was mainly concentrated in the Yellow River and Huaihe Riv-er(Huanghuai)Region,the area south of the Yangtze River Region,South China and other places,while northern China received more precipitation than normal.During the month,there were two heavy precipi-tation events,three severe convections,two cold air episodes and four sand-dust weather processes in to-tal.Among them,the cold air processes featured a wide range of impacts and a large cooling range.At the beginning of March,influenced by a cold wave,a severe snowstorm occurred in Shandong and the first se-vere convective weather event of the year took place in the Jiangnan and South China regions.Afterwards the sand-dust process at the end of the month incurred widespread strong sandstorm weather.关键词
