Domestic weather source
This sandstorm weather is caused by the sandstorm weather in Mongolia. The sandstorm weather in Mongolia directly invaded the northern and northwestern regions of China, which also brought great inconvenience to the mainland of China. The sandstorm weather in Beijing and Hebei is very obvious, which has a great impact this time.
The cause of the dusty weather in northern China Although this dusty weather is related to cold air, the specific reason this time is not in China, but the root of this dusty weather is the influence of Mongolian sandstorm, that is to say, some sand grains in the dusty weather in northern China came from abroad, and the power generated by cold air was swept to China by the wind.
Some people say that the sandstorm in northern Mongolia will enter China because of the cracks in the Three-North Shelterbelt, but this statement has no scientific basis. After all, the trees in the Three-North Shelterbelt can't resist the sandstorm of this scale at all.
The key reason is the high temperature and little precipitation in northern Mongolia, which leads to dry land in some areas. Moreover, the influence of Mongolian cyclone, that is, windy weather caused by cold air, created extremely favorable conditions for sandstorm weather in Mongolia, and it was precisely because of the strong wind caused by cold air that the dust was directly blown to China.
But I think the key reason is that people destroy nature and aggravate the occurrence of bad weather.
