The first cold wave came at 202 1, and the temperature dropped over 10℃ in some areas.

This winter is really unusual this year. It's hard to send away a cold wave, and then the first cold wave of 202 1 will be ushered in. It is reported that this cold wave will cause the temperature drop in most parts of China to exceed 10℃, and the Beijing early warning will usher in the lowest temperature of 2 1 century.

Cold Wave Blue Warning The Central Meteorological Observatory issued a cold wave blue warning at 06: 00 on June 65438+1October 14: It is estimated that the cold wave weather will affect most parts of China from June 65438+ 10/4 to June 17. There are 4 ~ 6 winds and 7 ~ 8 gusts in most parts of northern Xinjiang, eastern Northwest China and central and eastern China, and the daily average or minimum temperature will drop by 6 ~ 60. The temperature drop in northern Xinjiang, central and western Inner Mongolia, northern Gansu, central and northern Ningxia, northwestern Shaanxi, central and northern Shanxi, southeastern Northeast China, eastern Yunnan, southern Guizhou and southwestern Jiangnan can reach 10℃ or more. Due to the recent obvious temperature rise and high temperature, the cold wave weather has greatly cooled down, but the lowest temperature in most areas will be higher than the lowest temperature during the cold wave from June 6 to 8. The lowest temperature 0℃ line will be pressed south to the south of the Yangtze River to the north of South China, and the-10℃ line is located in central Hebei, southwestern Shanxi and central Shaanxi.

The temperature drop in many places exceeds 10℃. It is estimated that from 08: 00 on 14 to 08: 00 on 16, the temperature will drop by 6 ~ 8℃ in parts of southwestern and northern Xinjiang, central and western Inner Mongolia, northern Gansu, Ningxia, northwestern Shaanxi, central and northern Shanxi, northwestern Hebei, eastern Heilongjiang, central and eastern Jilin, most of Liaoning and Shandong Peninsula, among which northern Xinjiang. The above areas are accompanied by northerly winds of 4 ~ 6 grades, and the gusts can reach 7 ~ 8 grades.

Beijing will start the low temperature warning tomorrow. Affected by the cold wave, there will be strong winds and continuous low temperature weather in Beijing. According to the forecast of Beijing Meteorological Observatory, the lowest temperature in Beijing will be around-16℃ on the night of the 6th. According to statistics, the lowest temperature in Beijing since 2000 is-17℃. If the temperature in Beijing is below-17℃ during this cold wave, it will be the lowest temperature recorded since the 20th century.

In fact, the temperature of-16 and-17 degrees tomorrow is not too terrible, mainly because the wind is too strong, and the strong winds of grades 7 and 8 will blow even if you put on your pants. According to NOAA wind chill index, when the wind speed is 6m/s (about 12 knots), the somatosensory temperature will be-0/5℃.
