At 5:00 today, compared with 5:00 yesterday, affected by the cold wave, 8-12℃ cooling occurred in the eastern part of Northwest China, northern China, central and western Huanghuai, northeastern China, and Sichuan Basin. In western Shanxi, northern Hebei, northwest Beijing, central Liaoning, etc. The drop rate exceeds 16°C; some of the above-mentioned areas are accompanied by strong winds of magnitude 6 to 8, with gusts of magnitude 9 to 10, and gusts of magnitude 11 to 13 at individual sites in central and western Henan. At 5 o’clock today, the temperature 0℃ line is located in the north of Shandong, the south of Hebei, the south of Shanxi, and the south of Shaanxi.
The cold wave continues to affect the central and eastern regions of my country
Affected by the cold wave, it is expected that from 08:00 on November 7 to 20:00 on November 8, there will be a strong wind cooling process in North China and its southern regions: the temperature in most areas will drop by 8 to 10 degrees, the southeast of North China, the central and eastern Huanghuai, In parts of Jianghuai, the central and eastern Jiangnan, and the northern part of South China, the drop rate can reach 12～14℃, and the local area is above 16℃, accompanied by 4～6 northerly winds and gusts of 7～8; after cooling, the minimum temperature is 0℃ The line is located in the northern part of Jiangsu and Anhui, southern Henan and northern Sichuan.
