haze

Fine dust or salt particles dispersed through a portion of the atmosphere; the particles are so small that they cannot be felt, or individually seen with the naked eye, but they diminish horizontal visibility and give the atmosphere a characteristic opalescent appearance that subdues all colors.

haze
The condition in which horizontal visibility on the earth's surface is greater than 2 miles (3 km) but less than 3 miles (5 km). The reduced visibility may be caused by either suspended water droplets and/or dust or smoke particles. In the latter case, it is called dust haze or smoke haze, as the case may be. On weather charts, haze is depicted by the symbol image.

Haze
atmospheric turbidity from the presence of solid particles (smoke, soot, dust) suspended in the air. Haze sometimes reduces visibility to as little as 1 km and, when very heavy, to hundreds or only dozens of m. Haze occurs in steppe and desert regions; in other areas, it can be observed in air masses that come from steppes and deserts. Severe haze accompanies dry winds. Haze over large cities (smog) is due to pollution of the air with smoke and dust of local origin.
