Total economic losses from the 2007 snowstorm in southern China 5

Every year when the cold winter comes, it will be accompanied by heavy snowfall, and the degree of snow fall is different every year, when the snow falls very heavily, it will form a snow disaster, do you know which year the snow disaster occurred? How heavy is the snow? Let's find out!

It is reported that the snow disaster occurred in 2008, since January 3, 2008, China began to drop the temperature on a large scale, low temperatures, rain, snow, freezing one after another, people were caught off guard, almost more than 20 provinces were affected to varying degrees. As of 24 February 2008, the number of deaths had reached 129, the number of missing persons had reached 4, and the number of emergency resettlements had reached 1.66 million.

Under this huge snowstorm, the affected area of crops reached 100 million mu, the affected area was nearly 87.64 million mu, and 2,536 mu of farmland was not harvested, almost 10,000 houses collapsed in the heavy snow, and the damaged houses were disadvantaged. The snowstorm in 2008 caused economic losses of 100 million yuan. Many forests have been seriously damaged in the snow disaster, there are hundreds of millions of acres of forests destroyed, the number of wild animals under national key protection has reached 30,000 or frostbite, and the number of affected people has exceeded 100 million.

Some experts speculate that the reason for the snow disaster is related to the abnormal behavior of atmospheric circulation. It is reported that there is a blocking high pressure in the high-latitude Eurasian region, which has led to the invasion of China during the freezing period in the north, and at the same time, the warm and humid air from the Indian Ocean and other places has been transported to South China, and the convergence of cold and warm airflows has led to the existence of low-temperature rain, snow and freezing weather, and these various factors have contributed to the snow disaster. After the snowstorm in 2008, many airports were closed and departure times were changed, but most trains still depart on time.

If you encounter this kind of weather in the future, be sure to prepare in advance.

Since January 3, 2008, there have been widespread natural disasters such as low temperatures, rain, snow, and freezing in China. China's 20 provinces (autonomous regions and municipalities), including Shanghai, Jiangsu, Zhejiang, Anhui, Jiangxi, Henan, Hubei, Hunan, Guangdong, Guangxi, Chongqing, Sichuan, Guizhou, Yunnan, Shaanxi, Gansu, Qinghai, Ningxia and Xinjiang, have been affected by low temperature, rain and snow and freezing disasters to varying degrees.

As of February 24, 2008, 129 people had died and 4 were missing, and 1.66 million people had been urgently relocated. The affected area of crops was 100 million mu, 87.64 million mu was damaged, and 25.36 million mu was lost; 10,000 houses collapsed and 10,000 houses damaged; The direct economic loss due to the disaster was 100 million yuan.

The forest area was damaged nearly 100 million mu, and 30,000 wild animals under national key protection froze to death or suffered frostbite in the snowstorm; More than 100 million people have been affected. Seven provinces, including Anhui, Jiangxi, Hubei, Hunan, Guangxi, Sichuan and Guizhou, were the most severely affected.

Experts from China's National Meteorological Department pointed out that this widespread rain and snow process should be attributed to the atmospheric circulation anomaly related to the La Niña (anti-Virgin) phenomenon: the long-term meridional distribution of the circulation since January has caused frequent cold air activity, while the subtropical high is stronger and the southern branch trough is active, and the warm and humid air from the south and the cold air from the north converge in the middle and lower reaches of the Yangtze River to form strong precipitation. The stability of the atmospheric circulation caused the rain and snow to continue, and eventually led to the snow disaster.
