55
Fog occurs when:
Air temp near the ground reaches its dew point
Dew point is raised to existing temperature by added moisture to the air
56
Radiation fog
Occurs on calm clear nights when ground cools rapidly due to the release of ground radiation
57
Advection fog
Warm, moist air moves over a cold surface
58
Ice fog
Occurs when temps are much below freezing and water vapor turns directly into ice crystals
59
Upslope fog
Moist, stable air is forced up a terrain slope and cooled to its dew point by adiabatic cooling
60
Describe a frontal passage
Occurs when a front passes over a point on the surface reflected by a change in temp/dew point, wind speed, and atmospheric pressure
Often accompanied by clouds and precipitation
61
What is the temp above if there are ice pellets on the surface?
Freezing rain results from a temperature inversion
Temp above is warmer than temp below
Ice pellets indicate freezing rain above
