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 River (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 precipitation events, three severe convections, two cold air episodes and four sand-dust weather processes in total. 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 severe 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.
