What's the difference between the weather names of blowing sand, floating dust, floating dust and sandstorm?

According to experts from the Central Meteorological Observatory, sand blowing and sandstorms are caused by local or nearby dust blown by the wind.

Its * * * features are:

Visibility dropped significantly, and the sky was cloudy and yellow when it appeared. When cold air passes through the border or is affected by thunderstorms and squall lines, both of them are easy to appear in the northern spring.

The difference is:

There is strong wind in the sand-blowing weather, which affects the visibility between 1 km and1km;

The sandstorm is very windy, and the visibility is less than 1 km.

Floating dust is caused by fine particles such as dust storms in remote or local areas or floating dust after sand blowing.

Formed in the air, commonly known as "falling yellow sand." When it appears, the distant objects are khaki, the sun is pale or yellowish, and the visibility is less than 10 km, which generally appears before and after the cold air passes through.

Building engineering, house demolition, municipal facilities construction, material transportation and stacking, road excavation, maintenance and cleaning will all produce dust.
