On December 9 and 12, China ushered in the first blizzard and cold wave this winter, prompted by strong cold air, North China, Jianghuai and other regions ushered in the first heavy snow of this year, fluttering heavy snow, covering the earth!
Let's take Henan as an example, located in the Central Plains, ushered in the first blizzard of this winter. From 20:00 on December 10 to 05:00 on the 11th, heavy snow occurred in the west and north and central parts of Henan, and heavy snowfall occurred in some counties and cities in Zhengzhou, Luoyang, Jiyuan, Jiaozuo, eastern and southern Xinxiang, western Kaifeng, northern Xuchang, and northern Pingdingshan, Gongyi local blizzard;Other counties and cities experienced sleet or light to moderate rain.
For nowThe thickness of snow cover in most counties and cities in the west and north of Henan has reached more than 10 cm, and the thickness of snow in the south of Xinxiang, the west of Zhengzhou, the west of Kaifeng, and the south of Luoyang is more than 15 cm. The top three snow depths: Songxian 18 cm, Yuanyang 18 cm, Gongyi 17 cm.
Because of the arrival of this national-level blizzard and cold wave,The Henan region has also issued a notice of suspension of classes and operations. After all, this is a large-scale snowfall process in Henan in recent years, and the temperature has dropped very much, 1 4 degrees lower than the minimum temperature in a normal year, and the minimum temperature has dropped to nearly 15 degrees below zero, and the weather is unusually cold!
It's snowing in Beijing, it's snowing in Jinan, it's snowing in Shanxi, it's snowing in Shanxi, it's snowing in southern Hebei!This snow fell very heavily and widely, covering the area on both sides of the Yellow River!
The first round of heavy snowfall is basically over, and the cold air brought by the cold wave still exists, but the biggest impact is currently in Shandong!It's December 11thThere is a snowfall process on the Shandong Peninsula, light rain or sleet in other places, the weather is unusually cold, the north wind is blowing, and the cold is blowing!
In addition, there is heavy to heavy snowfall in the southeast of Northeast China and northern XinjiangOf course, under the influence of the southward movement of cold air, the Yangtze River basin and the places south of it ushered in sleet or light to moderate rain, and the cold body felt the cold of winter!
The first round of the blizzard passed,The second round of the blizzard is here again, the time is from December 13th to 15th, this time the blizzard is relatively high, the duration is relatively long, and the snowfall is mainly concentrated on December 14th!
December 13th, China has ushered in a wide range of rain and snow weather, this time the snowfall process is relatively uniform, the north is dominated by snowfall, and the south is dominated by rainfall. It is expected that the snowfall will be mainly concentrated in the central and eastern parts of Inner Mongolia, the southern part of Northeast China, North China, the northern part of Central China, the central and eastern parts of Xinjiang, the eastern part of **, the southern part of Qinghai, the western part of Gansu, the southwestern part of Sichuan, the northwest part of Yunnan and other regions
There was light to moderate rain in central China, Huanghuai, Jianghuai and southwest China, including moderate to heavy rain in western Yunnan
December 14 is the main time period for the second round of heavy snowfall！Due to the influence of the Siberian cold snap, the northern part of our country is dominated by snowfall, and there is heavy to heavy snowfall in local areas, and the wind force reaches 5 or 6!
According to the forecast map of snowfall,It is expected that there will be heavy to heavy snowfall in the central and southern parts of Northeast China, North China, and western Henan and ShandongThis is the second heavy snowfall this winter, and the snow is also the first largest snowfall this winter, and it is also the largest snowfall process!
At the same time, forHuanghuai, Jianghuai, and Southwest China, East and Northeast China have rainfall processes, and they have also ushered in heavy to heavy rain!Among them, there are heavy rains in the southern part of Shandong, the northern part of Jiangsu, the northern part of Anhui, Hubei, the northern part of Hunan, the southern part of Shaanxi, and the southern part of HenanIt is rare for such a heavy rainstorm to have such a heavy rain in the above areas!
The main reason is to be subjected toThe process of a blizzard and a storm formed by the warm and humid air currents of the south and the cold current of Siberia meet!This is the remarkable climate characteristic of this winter, with very active cold air and warm and humid air currents despite the high temperatures!
December 15th,As the strong cold air pushes east and south, the cold air has taken control of the atmosphere, so the rainfall and precipitation processes are also decreasing!
It is expected that the snowfall will be mainly concentrated in the eastern part of Inner Mongolia, the northeast region, the Shandong Peninsula, the north of North China, and the north of the Huai River in the Qinling Mountains, with light to moderate snowfall, especially in the southeast of Northeast China
Of course, the cold air pushes south and east, so there is light to moderate rain in the southern part of the Huanghuai, Jianghuai, and south of the Yangtze River, and heavy rain in some areasThis is the result of strong cold air!
According to experts**,This year, there will be more rain and snow in the Yangtze River and other areas to the south, or there will be snow disasters！Mainly this year, due to the El Niño phenomenon at the equator, the eastern Pacific Ocean has formed and will cause the ocean temperature to rise by at least 05 1 degrees, which makes the Pacific Ocean warm current, will make landfall in China to form effective rain and snow weather, coupled with the activity of strong cold air in the north, which will make the Yangtze River basin and the south of the area may have snow disasters!
To sum up, the first round of cold snap and blizzard weather this winter is basically over, followed by two sunny days, the Siberian cold snap hit again, which also brought stronger blizzard and cold wave to all regions in the central and eastern parts of our country.
It is expected to be on December 13 and 15, and the heavy snowfall is mainly concentrated on December 14, and the south is dominated by the rainfall process, with heavy rain in some areasThe north is dominated by snowfall, with heavy to heavy snowfall in some areasAnd the location of the blizzard still coincides in the southern part of Northeast China, North China, Shandong, Henan and other territories!
