fog

noun    (Concise Encyclopedia)

Cloud of small water droplets near ground level that is dense enough to reduce horizontal visibility to less than about 3,000 ft (1,000 m). Fog may also refer to clouds of smoke particles (smog), ice particles, or mixtures of these components. When visibility is more than 3,000 ft, the phenomenon is termed mist or haze, depending on whether it is caused by water drops or by solid particles. Fog is formed by the condensation of water vapour on condensation nuclei that are always present in natural air. The most stable fogs occur when the surface is colder than the air above. Fogs can also occur when cold air moves over a warm, wet surface and becomes saturated by the evaporation of moisture from the surface. Convection currents carry the fog upward as it forms, and it appears to rise as steam or smoke from the wet surface.
