There is dust in Beijing, Tianjin and Hebei 13 provinces and cities. Will it cool down in the south in March?
Of course, friends in many areas may have felt the cold weather in March, and now cold air is attacking the south in an all-round way. At the same time, from the perspective of cooling range, the cooling range in the south is stronger than that in the north, and the cooling range in some areas of Fujian, Guangzhou, Guizhou and Guangxi has reached 10 to 12 degrees.
So this kind of cooling is really rare in March. Compared with the first wave of strong cold air since March, the intensity of strong cold air is much stronger. Meanwhile, according to the time, the cold air will end in 1 days, and it is expected to end on March 2 1. At the same time, under the influence of cold air, there is still a lot of rain and snow. The rain and snow in the north mainly moves to the northeast, and there is a large range of rain and snow in the northeast of Inner Mongolia and Heijiliao, among which there is heavy snow or blizzard (10 ~16mm) in some areas in the east of Heilongjiang, and its intensity should not be underestimated.
Rainfall in the south has weakened, with only small to moderate rain in Hunan and Jiangxi. By the end of March 2 1, the snowfall in the northeast continued to move eastward, and the scope was further narrowed, while the rainfall in the south basically ended. However, the rain and snow basically ended, but the "cold wind" remained. At the same time, under the influence of cold air and strong wind, this is also the main reason for dust movement in China. According to the forecast, there are such dusty weather in northwest, north and central China, but the intensity is much smaller.
Dust has also appeared in Beijing, Tianjin and Hebei, and moved to Hubei and Sichuan in the south. You see, Chengdu is also shrouded in dust, but Chengdu is fine, with a rainy pattern, which may be alleviated. The comprehensive situation is that China 13 provinces, autonomous regions and municipalities will be affected by sand blowing or floating dust, so friends in the covered areas should be prepared. This is also the second wave of dusty weather since March. This is the initial rain and snow, cooling, dust and other weather activities. After this wave, this year's cold air is not over yet. It is expected that there will be another wave of cold air from March 26th to 28th.
But judging from the latest situation, the intensity of this cold air can be said to be minimal. After this round of strong cold air, China will enter a nationwide warming. On March 25, we can actually see that the next wave of cold air mentioned by the Central Meteorological Observatory is more obvious in Northeast China, but with the movement of cold air, the amplitude of this wave of cold air is not large, and it is mainly in Northeast China, North China and East China. The fluctuation is small, but
Under the activity of this wave of cold air, the main rain and snow is still in the northeast, so it is unlikely to be stronger than this wave of cold air. However, after it, we saw a new cold air mass appeared in the northwest, and the intensity was not low. At least around March 29th, Xinjiang has completely entered the cooling zone, so this wave of cold air may be postponed from March 26th to 28th. Of course, whether further observation is needed.
Generally speaking, there is indeed a lot of cold air this year, and the development of wave after wave is still highly frequent, which is much more active than our cold air in February all the year round. This is the next possible development of cold air. Of course, we still look at the present situation. Wind, rain, snow and dust all exist in China, which is relatively complicated. Of course, after this wave of strong cold air, the large-scale recovery is estimated to be basically over, so it won't be long.
