The weather conditions of sandstorms can be divided into

Sandstorm weather conditions are divided into five grades: floating dust, sand blowing, sandstorm, strong sandstorm and extra-strong sandstorm.

1, floating dust. Dust and fine sand float evenly in the air, making the horizontal visibility less than 10 km.

2. Blow sand. The wind blows up the dust on the ground, making the air quite turbid, and the horizontal visibility is in the range of 1 km to1km.

3. Sandstorm. Strong winds blow up a lot of dust on the ground, making the air very turbid, and the horizontal visibility is less than 1 km.

4. Strong sandstorm. Strong winds blow up the dust on the ground, making the air fuzzy and turbid, and the horizontal visibility is less than 500 meters.

5. Extremely strong sandstorm. Strong winds blow up dust on the ground, making the air particularly turbid, and the horizontal visibility is less than 50 meters.
