Haze, also known as haze, refers to the turbidity caused by the suspension of a large number of particles such as smoke and dust. The core substance of smog is dust particles suspended in the air, which are called aerosol particles in meteorology. Particles such as dust, sulfuric acid, nitric acid and organic hydrocarbons in the air can also make the atmosphere turbid, blur the vision and worsen the visibility. If the horizontal visibility is less than 10000 meters, the visual distance obstacle caused by this non-aqueous aerosol system is called haze or dust haze. Dust weather can be divided into four categories: floating dust, sand blowing, sandstorm and strong sandstorm. Floating dust: a weather phenomenon in which dust and fine sand float evenly in the air, making the horizontal visibility less than 10 km; Sand blowing: a weather phenomenon in which the wind blows up dust on the ground, making the air quite turbid and the horizontal visibility is within the range of 1 km to1km; Sandstorm: a weather phenomenon in which 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; Strong sandstorm: a weather phenomenon in which strong winds blow up dust on the ground, making the air turbid and the horizontal visibility less than 500 meters.
