Name the different types of Fog - ANSWER -Steam Fog Upslope Fog Precipitation Induced Fog Radiation Fog Advection Fog Describe Steam Fog - ANSWER -Cold, dry air moves over relatively warmer water and evaporates. (Can produce low level turbulence) Describe Upslope Fog - ANSWER -Warm, moist, stable air with wind pushes upslope and cools to its dewpoint. (Puts clouds on top of a mountain) Describe Precipitation Induced Fog - ANSWER -Warm rain/drizzle that falls through a cold layer of air and evaporates saturating the air. (Happens in the south more) Describe Radiation Fog - ANSWER -On a calm, cool, clear humid night the ground cools faster than the adjacent air, cooling the air to its dew point. Advection Fog - ANSWER -Warm, moist air moving over a cooler surface cooling it to its dewpoint. (Coastal fog generally)
