Why does visibility decrease when there is smog?
Haze, as its name implies, is fog and haze.
The aerosol system composed of dust, sulfuric acid, nitric acid and other particles in the air causes visual impairment, which is called smog.
Fog is an aerosol system consisting of a large number of tiny water droplets or ice crystals suspended in the air near the ground. It is the product of water vapor condensation in the air near the ground. The existence of fog will reduce air transparency and worsen visibility. If the horizontal visibility of the target drops below 1000 meters, the weather phenomenon of water vapor condensate suspended in the air near the ground is called fog.
