When did the freezing rain in the South start in 2008?
The freezing rain in the south in 2008 started on January 3, 2008.
China’s 20 provinces including Shanghai, Jiangsu, Zhejiang, Anhui, Jiangxi, Henan, Hubei, Hunan, Guangdong, Guangxi, Chongqing, Sichuan, Guizhou, Yunnan, Shaanxi, Gansu, Qinghai, Ningxia, and Xinjiang (districts and cities) are all affected by low temperature, rain, snow, and freezing disasters to varying degrees.
Experts from China’s National Meteorological Department pointed out that this large-scale rain and snow process should be attributed to atmospheric circulation anomalies related to the La Niña (Anti-El Nino) phenomenon: the long-term meridional distribution of circulation since January The cold air activities are frequent, and the subtropical high pressure is strong and the southern branch trough is active. The warm and humid air originating from the south and the cold air from the north meet in the middle and lower reaches of the Yangtze River, forming intense precipitation. The stability of the atmospheric circulation allowed the rain and snow to continue, eventually leading to this snow disaster.

Regional characteristics of freezing rain:
Freezing rain is more common in mountains and lake areas; more in southern China and less in northern China; more in humid areas and less in dry areas ; There are more mountainous areas than plains, with the most mountains.
