It’s the weekend!
Good weather is coming too!
For two days over the weekend, the influence of the cold air ended, and there was little rain or snow in most of the central and eastern regions.
With the blessing of sunshine, temperatures will rise significantly in both the north and the south, and the maximum temperature line of 10°C will quickly advance to central North China tomorrow and the day after tomorrow.
Especially in the south, the temperature rise will continue until the beginning of next week. The temperature will reach the recent high on the 4th and 5th, and the warmth will return. The highest temperature in Jiangnan will return to above 20℃, and in southern China it will reach above 25℃, and even hit 30℃.
Everyone can have a happy weekend~
In the large blank precipitation forecast map, I believe that many people's eyes are attracted by the snowfall in western Tibet and southwestern Xinjiang. The local snowfall even turns "purple"!
In the next three days, there will be heavy to heavy snowfall in western Tibet and southwestern Xinjiang. Among them, there will be heavy or extremely heavy snowfall in the high-altitude areas of Kashgar and Hotan in Xinjiang, western and southern Ali in Tibet, and southern Shigatse, with a cumulative snowfall of 30 to 40 mm. , in high-altitude areas it can reach 60 millimeters locally, and the new snow depth is 10 to 30 centimeters, and in high-altitude areas it can reach more than 50 centimeters locally.
The strongest snowfall period is from the night of the 1st to the 2nd. There are heavy to heavy snowfalls in some areas in the west and south of Ali, south of Shigatse and other places. There are heavy snowstorms or extremely heavy snowstorms (more than 42 mm) in high-altitude areas. The new snow depth is 10~ 25 cm, and above 45 cm in high altitude areas.
If you have no idea about such strong snowfall, let Tianzhuer use previous historical data to give you a feel.
In January 2020, Nyalam, Tibet, encountered a severe snowstorm. From 14:00 on the 16th to 14:00 on the 17th, the snowfall in Nyalam County reached 54.8 mm, and the snow depth reached 78 cm.
Why is there such heavy snowfall?
The first is the influence of the low vortex, which brings abundant water vapor in the Indian Ocean.
It can be seen from satellite cloud images that a large number of precipitation cloud systems have appeared in Pakistan and other places today.
As the westerly trough and vortex move eastward, the southwest jet stream in front of the trough strengthens, and coupled with the uplift of the terrain, the power and water vapor conditions cooperate better, creating this round of heavy snowfall in Tibet.
Moreover, the system moves slowly and lasts for a long time, causing the snowfall process to last for a long time.
Judging from the cumulative snowfall, the snowfall in western Tibet is extremely extreme, and on the 3rd, the ground wind in western Tibet increases, and wind and snow may occur.
This heavy snowfall will have an impact on local transportation, production and life, power and communication facilities, especially agriculture and animal husbandry. It is necessary to do a good job in keeping livestock cold and warm, stocking feed, and reinforcing pens.
