Last week, the strongest cold wave since this winter created heavy rain, snow and cooling weather in many places in China, and the cold air has made a comeback this week, which can be described as colder than colder. From today (December 18), a new round of stronger cold air will appear, which will bring 4 to 8 cooling to most of the central and eastern regions, with a local drop of more than 10, and many places will open a "freezing week". China Weather Network has launched a low temperature check-in calendar in big cities to see when the temperature in your home bottoms out.
The cold wave process just passed to most parts of our country brought obvious rain and snow, cooling and windy weather, more than 30% of the land area appeared more than 10 strong cooling, North China is 18 stations of the lowest temperature fell below the historical extreme value of December since the establishment of the station, at the same time, the middle and lower reaches of the Yangtze River north of the region appeared a wide range of rain and snow weather, 145 national stations of the daily snowfall broke through the historical extreme value of December since the establishment of the station.
The impact of the last round of cold wave on our country has just ended, and a new round of strong cold air has followed one after another since today. It is expected that the weather keyword in most parts of the country this week is still "cold", and before the 21st, the temperature in most areas will drop by 4 to 8, and the local cooling range will exceed 10.
Zhang Juan, a meteorological analyst at China Weather Network, said that although the cooling brought by this round of cold air is not as large as the previous round of cold wave, due to the current low base temperature, it can be said that it is colder than colder after cooling. In the next five days, the daily minimum temperature in Inner Mongolia and parts of Northwest China, North China, Northeast China, central and eastern Huanghuai, and eastern Jianghuai will be more than 7 lower than the same period in history. The temperature in many places in the north will bottom out from the 20th to the 21st, and some areas in North China and Huanghuai will be cold in the same periodIn the south, it will be a little later, and temperatures will reach their coldest in most areas on the 21st and 22nd.
Judging from the low temperature check-in calendar launched by China Weather Network, among the large cities in the north, the minimum temperature in Hohhot and the three provincial capitals in the northeast are running below minus 20, of which Harbin, Changchun, and Shenyang dropped to minus 29, minus 24, and minus 26 respectively on the 20th, all of which will break the lowest temperature since the second half of this year. In addition, the minimum temperature in Shijiazhuang, Yinchuan, Jinan, and Zhengzhou may also hit a new low since the second half of the year, and the cold degree is comparable to the coldest "39" and "49" in the year.
Not only in the north, the cold air will also drive straight down to South China, and it is expected that Line 0 will advance to the south of Jiangnan and the north of South China on the 22nd, which will also be the southernmost point of Line 0 since this winter. The minimum temperature in Hefei, Nanjing, Hangzhou, Wuhan, Shanghai, and Changsha will fall below freezing, and may hit a new low in the second half of this year, especially today and tomorrow under the influence of rain and snow, the body will feel particularly wet and cold.
This cold state will take a turn one after another after the 23rd. It is expected that the temperature in the central and eastern parts will slowly rise from the 23rd, and the temperature will rise to a state close to the same period of the year around the 25th.
China Weather Network reminds that the temperature in most of the central and eastern parts of the country continues to bottom out this week, and the weather is cold, so it is recommended that everyone go out to take out the thickest clothes to keep out the cold, wear scarves, hats, etc., and take measures to prevent colds and cardiovascular and cerebrovascular diseases. In the southern areas where there is no heating, it is necessary to pay attention to the safety of fire and electricity when using air conditioners, electric heaters, stoves, etc. for heating.
