It's the weekend! Good weather is coming!

Over the weekend, the impact of cold air ended, and rain and snow were scarce in most of the central and eastern regions.

With the blessing of sunshine, the temperature in the north and south will rise significantly, and the highest temperature of 10 will quickly advance to the central part of North China on the weekend. Especially in the south, the temperature will continue until the beginning of next week, the temperature will reach a recent high point on the 4th-5th, and the warmth will return, the maximum temperature in the south of the Yangtze River will return to more than 20, and the highest temperature in South China will reach more than 25 or even hit 30.

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, and the local snowfall has even become "purple"!

In the next three days, there will be heavy to heavy snowfall in the west and southwest of Xinjiang, including heavy snowfall or extremely heavy snowfall in the high-altitude areas of Kashgar and Hotan in Xinjiang, the west and south of Ali, and the south of Shigatse, with a cumulative snowfall of 30 40 mm, and local up to 60 mm in high-altitude areas, with a new snow depth of 10 30 cm and more than 50 cm in high-altitude areas.

The heaviest period of snowfall was from the night of the 1st to the 2nd, with heavy to heavy snowfall in parts of western and southern Ali and southern Shigatse, and heavy snowfall or extremely heavy snowfall (more than 42 mm) in high-altitude areas, with a new snow depth of 10 25 cm and more than 45 cm in high-altitude areas.

If you don't have an idea of such a strong snowfall, look at the previous historical data to feel it.

In January 2020, ** Nyalam suffered a heavy snowstorm, and from 14 o'clock on the 16th to 14 o'clock on the 17th, the snowfall in Nyalam County reached 548 mm, the snow depth reaches 78 cm.

Why is there such a strong snowfall?

The first is the effect of the low vortex, which brings abundant water vapor from the Indian Ocean. As can be seen from the satellite image, a large number of precipitation cloud systems have appeared in Pakistan and other places on March 1.

With the eastward movement of the westerly trough and the low vortex, the southwest jet in front of the trough strengthened, coupled with the uplift of the terrain, the power and water vapor conditions were relatively well coordinated, and this round of heavy snowfall was created. Moreover, the system moves slowly and lasts for a long time, resulting in a long duration of the snowfall process.

Judging from the cumulative snowfall, the snowfall in the west is extreme, and on the 3rd, the ground wind in the west increases, and there may be wind-blown snow.

This heavy snowfall will have an impact on local transportation, production and life, power and communication facilities, especially agriculture and animal husbandry, and it is necessary to do a good job in livestock cold and warmth, feed reserves, and enclosure reinforcement.
