It is blowing sand

Due to the dust and sand on the local or nearby exposed ground being blown up by the wind, the sky becomes turbid, yellow everywhere, and visibility is significantly reduced. This weather phenomenon is called blowing sand. Blowing sand generally occurs in the spring in the north (especially in the northwest). The atmospheric visibility is between 1 km and 10 km. It is a type of sand and dust weather.

Dust weather is a disastrous weather phenomenon. According to the horizontal visibility of the atmosphere, it can be divided into three levels, namely floating dust, blowing sand and sandstorms. ?

Floating dust: Sand or dust suspended in the atmosphere, with horizontal visibility less than 10 kilometers.

Blowing sand: Strong winds stir up sand or dust on the ground, the air is quite turbid, and the horizontal visibility is 1 to 10 kilometers. ?

Sandstorm: Strong winds blow up dust and sand on the ground, the air is very turbid, and the horizontal visibility is less than 1 km. When the horizontal visibility is less than 500 meters, it is a strong sandstorm.

Extended information:

During sand blowing weather, the wind is strong, the air is turbid, and visibility is reduced, which often produces many adverse effects:?

1. Sand everywhere The stone is diffuse and the air is turbid, making people choke and squinting, and easily induce respiratory diseases.

2. A large amount of sand and dust blocks the sun and reduces solar radiation, making people feel depressed and affecting their work and study.

3. Visibility is significantly reduced, which affects vehicle travel and can easily lead to frequent traffic accidents, highway closures, and the inability of aircraft to take off or land normally. In severe cases, it can cause the glass of cars and train carriages to be damaged, or even suspend operations. Or derailed.
