Fog and dew definition
WebThe term “smog” (from the words “smoke” and “fog”) is widely used for conditions where fog and heavy air pollution are present, with chemical reactions between the fog droplets and various pollutants. Reduction in visibility depends on the structure of the fog, and especially on the number density and size distribution of the droplets.

WebCondensation can occur when the dew point is below freezing or 0° C, and it can also occur when the dew point is above freezing. The types of condensation can be divided into two groups in this way: (1) When the dew point falls below freezing, frost, snow, and certain clouds occur. (2) When the dew point rises above freezing, dew, mist, fog ... pcsh-b-crWebJun 25, 2009 · A fog that forms when outgoing longwave radiation cools the near-surface air below its dew point temperature. Rain Induced Fog When warm rain falls through cooler air, water evaporates from the warm rain. It subsequently condenses in the cool air forming fog. Such fog can be quite dense. It generally will persist as long as the rain continues. pcshcr1WebHowever, a fog is different because the water vapour reaches its dew point (the temperature at which it turns back into water droplets) right over the surface of the earth.
