China Weather News’ Annual “Overlord” Cold Wave Is Coming! On the morning of December 28, the Central Meteorological Observatory updated the cold wave alert to the highest orange alert level, and most areas of the country will “freeze crying.” China Weather.com has published a map of the frozen line process. An image shows when the frozen line crosses the Yangtze River and reaches Yunnan, Guangxi and Guangdong.
The strongest cold wave since this winter has broken out. The Central Meteorological Observatory issued another orange cold wave warning after a lapse of four years. From 28 to 31, the temperature in most central and eastern regions will drop by about 10 ° C, and the local temperature drop can reach more than 16 ° C. This cold wave has a rapid cooling rate and some areas They have a “cliff-style” cooling. It will be more intense than the January 2016 cold snap. From this perspective, this year’s New Year’s Eve cold snap will be comparable to the “Overlord” cold snap.
As the cold snap moves south, the lowest temperature freezing line of 0 ℃ will push south step by step. On the morning of the 29th, the lowest temperature 0 ° C line will be located in northern Jiangsu, central Henan, southern Shaanxi and central Sichuan. At this time, the minimum temperature in most of Heilongjiang and Jilin will be below -20 ℃, and the minimum temperature in parts of the northwest will also be below -10 ℃. However, Jiangnan and other places have not been affected by the cold snap. The lowest temperature is above 0 ℃, and some areas are above 10 ℃.
It is expected that on the morning of the 30th, the impact of the cold wave will cross the Yangtze River, and the 0 ℃ line of the lowest temperature will push south to the south of Zhejiang, the northwest of Jiangxi, the south from Hunan, southern Guizhou and northern Yunnan. The temperature in the middle and lower reaches of the Yangtze River and elsewhere will drop in a “cliff” fashion, with the minimum temperature below freezing, and in some cities even below -5 ° C. Among the provincial capitals , Hefei, Wuhan, Nanjing, Shanghai, Hangzhou, Changsha and Nanchang will all have the lowest temperatures since this winter.
On the morning of the 31st, the frozen line will continue to move south, reaching the western part of Fujian, north of Guangdong and north of Guangxi. By then, more than 80% of the earth may be “frozen”. In places like Guangzhou, Nanning, Fuzhou, etc., although the lowest temperature is above 0 ℃, it is also below 5 ℃, and the cold will be very obvious.
Hu Xiao, chief meteorological analyst at China Weather.com, said that the absolute temperature of the New Year’s Eve cold snap is not as low as that of the cold snap in late January 2016. take into account that the cold wave will cool down and the wind will be higher and the cold will increase. The strong wind will make the situation worse.
Hu Xiao recalled that there is a possibility of low temperature and cold damage during this cold snap, and a good job needs to be done to preserve heat and prevent wind on vegetables. Farmers should cover the crops with straw quilts in time. Heating equipment can be used if conditions permit. Shandong, Anhui, Jiangsu and other places Be careful of damage to the shed film. Furthermore, since winter is a period of high incidence of respiratory diseases, the low temperature environment is conducive to the survival and spread of the virus. Therefore, under the influence of this cold snap, the public should pay special attention to hot and cold weather, beware of colds, and take precautions when going out.
