Abstract:
The main characteristics of the general atmospheric circulation in October 2024 are that the polar vortex was distributed in a multipolar pattern. The mid- and high- latitude circulation in the Northern Hemisphere presented a multi-wave distribution, while in the Eurasian region it presented a “two troughs and one ridge” pattern. The Western Pacific subtropical high was stronger and the location was more westward and northward. In October, the monthly mean temperature was 11.6℃, 1.0℃ higher than that of the same period in normal years (10.6℃). The monthly average precipitation was 39.0 mm, 10% more than the normal (35.6 mm). During this month, there were six cold air processes, five major precipitation processes, and three typhoons affecting China. From September 29 to October 3, the cold air process was a national cold wave, and the three main precipitation processes were related to typhoons.
