Mist makes a light beam visible from the side via refraction and scattering on the suspended water droplets, and rainbows can be possibly created. In the United Kingdom, the definition of fog is visibility less than 100 m (330 ft) on the surface for driving purposes, while for pilots the distance is 1 km at cruising height. The phenomenon is called fog if the visibility is 1 km (1,100 yd) or less. One main difference between mist and fog is visibility. Fog is denser, more opaque, and generally lasts a longer time, while mist is thinner and more transparent.ĭescription A light morning mist on Lake Suolijärvi in Hervanta, Tampere, FinlandĬloud cover is often referred to as "mist" when encountered on surfaces of mountains, whereas moisture suspended above a body of water, cleared or marsh area is usually called "fog". These two phenomena differ, but share some commonalities similar processes form both fog and mist. Mist is commonly confused with fog, which resembles a stratus cloud lying at ground level. Thus even such unusual sources of nucleation as small particulates from volcanic eruptions, releases of strongly polar gases, and even the magnetospheric ions associated with polar lights can in right conditions trigger condensation and the formation of mist. The formation of mist, as of other suspensions, is greatly aided by the presence of nucleation sites on which the suspended water phase can congeal. It can also occur as part of natural weather, when humid air cools rapidly, notably when the air comes into contact with surfaces that are much cooler than the air (e.g. It can be created artificially with aerosol canisters if the humidity and temperature conditions are right. It is most commonly seen where water vapor in warm, moist air meets sudden cooling, such as in exhaled air in the winter, or when throwing water onto the hot stove of a sauna. Physically, it is an example of a dispersion. Mist is a phenomenon caused by small droplets of water suspended in the cold air, usually by condensation.
