Did the strongest cold wave weather in the history of China occur in late 1 1987 10?

No, the strongest cold wave occurred on 20 16.

The temperature is below 0℃ in most areas north of South China,-10 ~ 3℃℃ in most parts of Guizhou and eastern Yunnan, -2 ~ 9℃ in Guangdong, Guangxi and western Yunnan, and 5 ~ 9℃ in Hainan. As of 14, the temperature in most parts of the south has obviously rebounded. The temperature in Jianghuai, most parts of the south of the Yangtze River, Guizhou and Sichuan is 1 ~ 7℃, and the temperature in most parts of South China is 6 ~ 15℃.

In view of this cold wave process, He Lifu believes that as a typical extreme weather event, the average cooling rate of this cold wave is not very strong, but from the perspective of causing low temperature in the south and snowfall in South China in a short time, it should be rare, at least the strongest cold wave process in the past 20 years.

Extended data:

There have been several extremely cold winters in the history of our country, and generally such weather is mainly related to La Nina phenomenon.

Formation process

The southeast wind blows the seawater heated by the sun to the western Pacific Ocean, resulting in higher sea level in the west than in the east and higher sea temperature in the west. The air flow in the eastern equatorial Pacific sinks, and the west begins to rise, and the sea water movement becomes more intense, which intensifies the pressure drop. The accumulation of humid air forms typhoons and tropical storms, and the bottom sea water in the east turns up, which leads to the cooling of the sea water in the East Pacific.

La Nina's influence is far less than that of El Ni? o. Usually, whenever El Ni? o occurs, La Nina may occur in the next few years, and it takes about four years to transform the two.

Xinhuanet-The "strongest cold wave" in China ended on 25th, and the lowest temperature at 82 weather station broke the history.
