When the strongest cold wave strikes, it will encounter "cliff-like" cooling, and which areas will have obvious cooling?

According to the news released by China Meteorological Observatory recently, China is about to usher in a cold wave and will continue to issue a yellow warning for the cold wave. Cooler? Cliff type? Downward, as of 8: 00 today, China ushered in the first gale cooling from northwest to southeast, with the cooling rate as high as 10 degrees, and the cooling rate in North China, Northwest China, Northeast China, Huanghuai and Jianghuai was as high as 14 degrees.

The strongest cold wave is a natural weather phenomenon and belongs to disastrous weather. The principle of cold wave formation is that high-latitude cold air invades the middle and low dimensions on a large scale, causing intense cooling activities. When a cold wave strikes, it will cause windy, rainy and snowy weather along the way, leading to strong cooling. Because the cold wave will bring great cooling, it will cause frost, snowstorm and rainfall, which will have a great impact on agriculture, transportation and electricity. This cold wave is the strongest cold air since autumn this year. The temperature will gradually drop from northwest to southeast, and the overall temperature will drop by 8- 16℃. At present, the cold wave is still in Xinjiang, and it will come to South China on165438+1October 8.

The prominent change of cold wave is the more prominent change brought by cold wave belt. In addition to the severe cooling situation, it will also be accompanied by strong winds, rain and snow. Every time a cold wave strikes, there will be nationwide cooling, and other provinces will be affected except the south-central Qinghai-Tibet Plateau with high altitude and parts of western Yunnan, that is, the southernmost tip of Hainan. The cooling caused by cold wave is usually above 8- 10℃. This cold wave has an impact on agriculture, transportation, electric power and people's monitoring, so we need to pay attention to prevention.

Preventing the strong wind brought by cold wave will seriously threaten the navigation in coastal waters, so ships must be at safe docks in cold wave weather to reduce the influence of themselves and other ships. Residents should close the doors and windows again, pay attention to adding clothes to keep warm, especially the elderly and infirm patients, and pay attention to anti-skid when going out. Herdsmen drive outdoor livestock into sheds to feed them to prevent losses caused by freezing to death.
