What dusty weather is there?

Meteorologists say that dusty weather refers to a weather phenomenon in which strong winds roll up a lot of dust from the ground, which makes the air turbid and the horizontal visibility drops obviously. Sandstorm weather can be divided into three categories: floating dust, sand blowing and sandstorm.

Floating dust: sand or soil particles uniformly suspended in the atmosphere (mostly from other places, or left in the air after local sand blowing and sandstorm weather), so that the horizontal visibility is less than 10 km.

Sand blowing: 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.

Sandstorm: Strong wind blows up dust on the ground, making the air very turbid, and the horizontal visibility is less than 1 km. When the horizontal visibility is less than 500m, it is defined as a strong sandstorm.
