Did the strongest cold wave in China’s history occur in late November 1987?

No. The strongest cold wave occurred in 2016.

Most areas north of South China have temperatures below 0°C. Most of Guizhou and eastern Yunnan are -10~3°C, Guangdong, Guangxi and western Yunnan are -2~9°C, and Hainan are 5~9°C. . As of 14:00, the temperature has risen significantly in most parts of the south. The temperature in the Jianghuai, most of Jiangnan, Guizhou, Sichuan and other places is 1 to 7°C, and most of South China is 6 to 15°C.

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

Extended information:

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

Formation process

The southeast trade wind blows the seawater heated by the sun to the western part of the Pacific Ocean, causing the sea level in the west to be higher than that in the east. The seawater temperature in the west increases, and the air flow in the eastern part of the equatorial Pacific It sinks, and begins to rise in the west. The movement of seawater becomes more intense, which intensifies the drop in air pressure. The accumulation of moist air forms typhoons and tropical storms. The bottom seawater in the east turns up, causing the seawater in the eastern Pacific to cool.

The impact of La Niña is far less than that of El Niño. Under normal circumstances, whenever an El Niño phenomenon occurs, a La Niña phenomenon is likely to occur in the next few years. It takes about four years for the two to transform into each other.
