The cold wind blows the surface like a knife, and the snow is difficult to dissipate and the water turns into ice. Last week, the strongest cold wave since this winter swept through China, and most of the central and eastern parts of the country experienced seasonal cooling, and the temperature in many places was significantly lower than normal. After this wave of cold waves, the winter in the north is even colder, and the winter in the south of the Yangtze River does not only stay at the physical level, but also enters the winter in the meteorological sense in many places. According to the latest national winter progress map released by China Weather Network, the current winter territory has expanded significantly to the south compared with the beginning of December, covering three-quarters of China's territory.
The footsteps of winter arrive at South Ridge.
Shi Yan, a meteorological analyst at China Weather Network, said that in early December this year, most of China was significantly warmer, resulting in the postponement of the winter process in many places in the south. From the 13th to the 16th, the strongest cold wave since this winter hit, and most of the central and eastern regions ushered in a big jump in temperature from north to south. After the cold wave, the temperature in most parts of the central and eastern parts of the country was significantly lower than that of the same period in normal years, and some areas in North China, Jianghuai, Jiangnan and other places were lower than 5, which boosted the winter process in many places in the south of the Yangtze River.
According to the latest winter process map released by China Weather Network, as of December 19, the forefront of winter has reached the southern part of the Yangtze River and the southern part of Guizhou, which covers three-quarters of China's land and occupies a dominant position in the seasonal map. It is already deep winter in most of the north, and the lake is frozen and the snow is difficult to removeMost of the south of the Yangtze River has completed the transition between autumn and winter in the process of the cold wave that has just passed, and most of Jiangxi, Zhejiang, Hunan and other provinces have collectively entered winter.
This year, many places in the south of the Yangtze River started winter later than the same period in normal years. Shi Yan said that among the provincial capital-level cities, Changsha on December 11, Hangzhou and Nanchang entered the meteorological winter on December 12, about a week later than usual.
Most of southern China is still some way from the real winter. However, in the next few days, northern Guangdong, northern Guangxi, Fujian and other places can briefly experience the breath of winter, and the minimum temperature in Fuzhou on the 22nd and Haikou on the 24th will drop to 4 °C and 8 °C respectively, or experience the coldest moment since this winter.
Temperatures remained low until the weekend.
Today and tomorrow, the cold air that is affecting our country will continue to exert its power, and the temperature will drop in various places, and the temperature in most of the central and eastern parts will drop by 4 to 8. From the 21st to the 22nd, the freezing line will be pressed south to the northern part of South China, and the daily minimum temperature or average temperature in some areas of North China, Huanghuai and other places may exceed the extreme value of the same period in history.
Around the 25th, most parts of China will usher in a brief warming, and the temperature in the central and eastern parts of the country will turn from a significantly low level to the same level as the same period of the year. However, from the 26th to the 27th, a strong cold air will be "shipped" again, affecting the central and eastern parts of China, when the temperature in most parts will drop by 4 to 8, and some areas can exceed 10.
China Weather Network reminds that at present, on the seasonal map of our country, winter is already a proper overlord. At this time, not only the cold air is frequent, but also the intensity is strong, and there are many cold waves to disturb, please continue to do a good job of cold protection and warmth. At present, many places in our country are experiencing cold weather over 3949, especially in many places in the north The temperature will be below the freezing point all day, and the snow has not disappeared in the early stage.
