The Atmosphere - Chapter 2: Fog Flashcards
A cloud with its base at or very near the ground
Fog
What is the difference essentially between fog and clouds?
Method, place of formation
Clouds result when air rises and cools adiabatically, but fogs are the consequence of ______ or ______
radiation cooling
movement of air over cold surface
What forms when moist warm air is blown over a cool surface?
Advection fog
This type of fog forms on cool, clear, calm nights
Radiation fog
This type of fog forms when relatively humid air moves up to a gradually sloping plain or up the steep slopes of a mountain
upslope fog
This type of fog happens when cool air moves over warm water (looks like its name)
Steam fog
How does frontal or precipitation fog form?
When frontal wedging occurs and warm air is lifted over colder air. If the resulting clouds yield rain and the cold air below is near the dew point, enough rain will evaporate to make fog
