Original title: It’s colder! Three groups of cold air hit 20 provinces, autonomous regions and municipalities, temperatures may break the lowest this winter
After New Years Day, the cold air quickly took over. In the next ten days (from January 4 to 13), there will be three cold air blasts that will frequently plague China, between which the local temperature will drop more than 10 ℃ from January 6 to 8. Under the continuous suppression of cold air, most areas in China will get colder and colder. The temperature in 20 provinces, autonomous regions and municipalities may reach a new low this winter, and the degree of coldness is no less than the cold wave of late 2020!
The combination of three cold air blows is as cold as the cold snap of late 2020
This week three currents of cold air will follow. The first is from 4 to 5. The force of this cold air is relatively weak. It mainly affects the eastern part of Northwest China, North China, Huanghuai, Jianghuai and other places. The temperature generally drops 4 ~ 6 ° C, precipitation is still scarce. The second wave of cold air is from 6 to 8. This cold air force is relatively strong. The central and eastern regions will experience a cooling of 6 ~ 8 ℃ from north to south, and the local temperature will exceed 10 ℃. Some areas have 4 ~ 6 levels. Winds from the north, gusts of magnitude 7-9.
From the 10th to the 12th, there will be more cold air to the south which will affect our country, and the temperature in the central and eastern regions will drop 4 ~ 6 ℃. After that, the force of the cold air will weaken. Except in the northeast and east of Inner Mongolia, the temperature in other parts of the center and east will gradually increase from a continuously low state to almost normal.
According to Hu Xiao, chief analyst at China Weather Network, the main reason for the recent successive cold air attacks is that the Siberian high pressure remains strong. Particular attention should be paid to the second cold air. Since the time is 2939, the base temperature is very high. Low, cooler than the cold snap of late 2020. Under the continued suppression of cold air, the temperature in the central and eastern regions will again drop to a significantly lower level. The temperature in 20 provinces, autonomous regions and municipalities could reach a new low this winter.
Judging from the higher temperature, the northern part cools mainly to a low point of 6 to 7. Among the big cities, the highest temperature in Harbin, Changchun and Hohhot can reach -20 ℃; Jinan -8 ℃ is very rare low temperature in January, or exceeds extreme temperature during overlord’s cold snap in 2016; while Tianjin and Beijing speed drops to -8 ° C, along with the whistling of the north wind, the wind chill effect is obvious and the body feels “frozen”.
The heat in the south can last two to three days, mostly bottoming out from 7 to 8, when the highest temperature in the middle and lower reaches of the Yangtze River will drop from about 10 ° C to about 0 ° C, and in southern China from 20 ° C to about 10 ° C. Above and below ℃, the cumulative cooling range can reach about 10 ℃. After the temperature drops, Hangzhou may experience the first highest temperature of less than 0 ℃ this winter. Shanghai and Nanjing will once again experience subzero cold throughout the day, and Fuzhou and Guangzhou will experience the coldest period since this winter. For friends from the south, the temperature difference between the beginning of this week and the last part of the week is relatively large, and the cold will increase in the morning and evening hours. You should pay attention to stay warm when you leave early and come back late.
The pattern of little rain and snow across the country is related to a weak flow of warm and humid air.
Due to the weaker southern branch and poor water vapor transport conditions, the recent cold air process is dominated by cooling and precipitation is weak, mainly concentrated in the south. Light snow or sleet is expected in eastern southwestern China, most of Jiangnan, southern Gansu, southern Shaanxi, and western Hubei from 6 to 7, and light rains in parts of southeast China. Jiangnan and southern China.
Hu Xiao recalled that this Friday our country will mark the beginning of the coldest day of the year “March 9”. Three strands of cold air bless the severe cold of “March 9”. The coldest season of the year is here, and our friends to the north and south must keep warm. Stay warm then stay warm, put on thicker cold gear, cover your ankles, watch out for wind, cold and frost, and watch out for colds.
