In mid-December, a strong cold air affected most of China from north to south, among which Beijing-Tianjin-Hebei and the surrounding Shanxi, Henan, Shandong, Hebei and other 7 provinces and cities suffered the coldest week since the second half of this year, and the minimum temperature in some areas even fell below the extreme value of the same period in history. However, as the cold air weakens and moves eastward, the temperature in these areas will gradually warm up from the 22nd, and it is expected that the temperature in most areas will return to normal or high levels by the 25th.
According to the data of the ** Meteorological Observatory, from December 14th to 20th, the average temperature or daily minimum temperature of Beijing-Tianjin-Hebei and the surrounding 7 provinces and cities was more than 5 lower than that of the same period in history, of which some areas in the central and western parts of Inner Mongolia, North China, Liaoning, eastern Huanghuai, Jianghuai, and northern Jiangnan were lower than 7, and the minimum temperature 0 line will be located in the southern part of Guizhou to the northern part of South China. The intensity and duration of this cold air exceeded that of a strong cold air process at the end of November this year, and it was also the strongest cold air process since the second half of this year.
Under the influence of this cold air, many regions in Beijing-Tianjin-Hebei and the surrounding 7 provinces and cities have refreshed the lowest temperature records since the second half of this year, and some areas have even broken the lowest temperature records for the same period in history. For example, the minimum temperature in Beijing dropped to -12 on December 19, the lowest since the second half of the year and the lowest since December 2010The minimum temperature in Tianjin dropped to -11 on December 18, the lowest since the second half of the year and the lowest since December 2012The minimum temperature in Hebei province dropped to -23 on December 19, the lowest since the second half of the year and the lowest since December 1961The minimum temperature in Shanxi province dropped to -16 on December 19, the lowest since the second half of the year and the lowest since December 2012The minimum temperature in Henan province dropped to -11 on December 19, the lowest since the second half of the year and the lowest since December 2012The minimum temperature in Shandong province dropped to -18 on December 19, the lowest since the second half of the year and the lowest since December 1961.
This cold air process not only brought cold weather to Beijing-Tianjin-Hebei and the surrounding 7 provinces and cities, but also had a certain impact on local transportation, agriculture and life. Due to the low temperature, there are problems such as icy roads, frozen and cracked water pipes, and insufficient heating in some areas, which have brought inconvenience to the travel and life of citizens. In addition, due to the drying effect of cold air, air quality has also decreased in some areas, and some areas in Beijing, Tianjin, Hebei and other places have experienced mild to moderate haze. In agriculture, due to the sudden attack of cold air, winter wheat, vegetables and other crops in some areas have been threatened by frost damage, and protective measures need to be taken in time.
However, fortunately, the impact of this cold air will gradually end this week, with the weakening and eastward movement of cold air, the temperature in Beijing-Tianjin-Hebei and the surrounding 7 provinces and cities will gradually warm up from the 22nd, and it is expected that by the 25th, the temperature in most areas will return to normal or high levels. According to the forecast of the ** meteorological observatory, from the 22nd to the 25th, the daily maximum temperature in Beijing, Tianjin and Hebei and the surrounding 7 provinces and cities will increase day by day, of which the daily maximum temperature in Beijing will rise from -3 on the 22nd to 3 on the 25th, the daily maximum temperature in Tianjin will rise from -1 on the 22nd to 5 on the 25th, the daily maximum temperature in Hebei Province will rise from -5 on the 22nd to 4 on the 25th, and the daily maximum temperature of the high-quality author list in Shanxi Province will rise from -5 on the 22nd to 5 on the 25th The daily maximum temperature in Henan Province will rise from -1 on the 22nd to 7 on the 25th, and the daily maximum temperature in Shandong Province will rise from 0 on the 22nd to 7 on the 25th. As the temperature rises, the winter in these areas will become warm and comfortable, and citizens can appropriately increase outdoor activities to enjoy the warm winter sun.
Meteorological experts reminded that although the temperature will gradually rise, the temperature in the morning and evening is still low, and the public still needs to pay attention to cold protection and keep warm, especially the elderly and children and other people with weak physique, to avoid cold.
