Sea Fog Common advection fog caused by transport of moist air over a cold body of water. Improvement in visibility cannot be expected until the rain stops or moves out of the affected area. Since temperature rises little during the day, there is little diurnal variation in rain induced fog. It generally will persist as long as the rain continues. It subsequently condenses in the cool air forming fog. Rain Induced Fog When warm rain falls through cooler air, water evaporates from the warm rain. Radiation Fog A fog that forms when outgoing longwave radiation cools the near-surface air below its dew point temperature. At temperatures warmer than -30Â☌, these sources can cause steam fog of liquid water droplets, which may turn into ice fog when cooled (see frost smoke). Sources are the open water of fast-flowing streams or of the sea, herds of animals, volcanoes, and especially products of combustion for heating or propulsion. Ice fog is rare at temperatures warmer than -30Â☌, and increases in frequency with decreasing temperature until it is almost always present at air temperatures of -45Â☌ in the vicinity of a source of water vapor. The sun is usually visible and may cause halo phenomena. It occurs at very low temperatures, and usually in clear, calm weather in high latitudes. Ice Fog (Also called ice-crystal fog, frozen fog, frost fog, frost flakes, air hoar, rime fog, pogonip.) A type of fog, composed of suspended particles of ice partly ice crystals 20 to 100 micron inĭiameter, but chiefly (especially when dense) ice particles about 12–20 micron in diameter, formed by direct freezing of supercooled waterĭroplets with little growth directly from the vapor. GF) Fog produced over the land by the cooling of the lower atmosphere as it comes in contact with the ground. Freezing Fog A fog the droplets of which freeze upon contact with exposed objects and form a coating of rime and/or glaze. Fogbow A rainbow that has a white band that appears in fog, and is fringed with red on the outside and blue on the inside. Fog is often hazardous when the visibility is reduced to ¼ mile or less. F) Fog is water droplets suspended in the air at the Earth's surface. Dense Fog Advisory Issued when fog reduces visibility to 1/8 mile or less over a widespread area.įor marine products: An advisory for widespread or localized fog reducing visibilities to regionally or locally defined limitations not to exceed 1 nautical mile.Įvaporation-mixing Fog Fog that forms when the evaporation of water raises the dew point of the adjacent air.
