1, word explanation:

Dust flying in the air or attached to the surface of objects; A lot of tiny dust floats in the air, which makes the sky yellow. Most of these floating dust are caused by sandstorms and sand blowing.

2. Network explanation:

Floating dust weather, that is, the lowest intensity sandstorm, is a weather phenomenon formed by the generation and transmission of long-distance sandstorms or local sand blowing weather. The strength is weakened, and after the coarse particles in the dust settle by gravity, the fine particles are continuously transported and float in the air. When the wind speed continues to decrease, the suspended dust particles will settle to the ground, so it is commonly known as "falling yellow sand".

In dusty weather, distant objects are khaki and the sun is pale or yellowish; The wind speed is not very high, below level 4; Visibility is less than 10 km and greater than 10 km. Floating dust and falling dust worsen the surrounding environment and have an important impact on human health, especially the respiratory system.
