Since June 38, 2008+10/October 3, natural disasters such as low temperature, rain, snow and freezing have occurred in China. China, Shanghai, Jiangsu, Zhejiang, Anhui, Jiangxi, Henan, Hubei, Hunan, Guangdong, Guangxi, Chongqing, Sichuan, Guizhou, Yunnan, Shaanxi, Gansu, Qinghai, Ningxia, Xinjiang and other 20 provinces (autonomous regions and municipalities) are all affected by low temperature rain, snow and freezing disasters to varying degrees.

As of February 24th, 2008, 29 people died 1.29, 4 people were missing, and 1.66 million people were resettled urgently. The affected area of crops was 65.438+0.78 billion mu, resulting in 87.64 million mu of disasters, with no harvest of 25.36 million mu; 485,000 houses collapsed and 6,543,800 houses were damaged; The direct economic loss due to the disaster is 1.5 1.65 billion yuan.

The damaged forest covers an area of nearly 279 million mu, and 30,000 national key protected wild animals were frozen to death or frostbite in the snowstorm. The affected population has exceeded 1 100 million. Seven provinces, including Anhui, Jiangxi, Hubei, Hunan, Guangxi, Sichuan and Guizhou, suffered the most.

Experts from the National Meteorological Department of China pointed out that the large-scale rain and snow process should be attributed to the abnormal atmospheric circulation related to La Ni? a (anti-El Ni? o) phenomenon: the long-term meridional distribution of circulation since June+10 in 5438 has made cold air activities frequent, while the subtropical high is strong, and the south branch trough is active. Warm and humid air from the south meets cold air from the north in the middle and lower reaches of the Yangtze River, resulting in heavy precipitation. The stability of atmospheric circulation made the rain and snow weather last, which eventually led to the occurrence of snowstorms.

Extended data:

Melting snow flows into the ocean, and disasters spread beyond land. On February 8th (the second day of the New Year's Day), a large number of fish died suddenly in Penghu Islands in the Taiwan Province Strait, including 58 families, 183 species, and even many new species. About10.5 million tons of dead fish were cultured, and the loss was about NT$10.8 billion yuan. According to the exploration of marine experts, fish carcasses are piled up along the coast like hills, and fish carcasses are everywhere on the seabed. In the waters with a water depth of less than 20 meters, "all invertebrates are spared". In addition, fish farmers in Guangdong Province and Hong Kong are also affected by the cooling of seawater, resulting in a large number of fish deaths.
