What is the word "haze"? What do you mean?

In history books, the word "haze" is used to indicate the weather with sandstorms, and there is a saying that "wind and rain are haze". Haze is a weather phenomenon in meteorology, which refers to the phenomenon that a large number of extremely fine dry dust particles float evenly in the air, making the air with horizontal visibility less than 10 km generally turbid. Mist makes bright objects in the distance slightly yellow and red, and dark objects slightly blue. When water vapor condensation intensifies and air humidity increases, haze will turn into fog. The formation of smog is closely related to the discharge of pollutants. In cities, motor vehicle exhaust and other smoke and dust emission sources emit micron-sized particles, which stay in the atmosphere. When adverse weather such as inversion and still wind appears, smog is formed.
