Advection Fog

Advection fog is a type of fog. When warm, moist air moves horizontally across a cold surface, the air is cooled to the dew point, and fog forms because of it. Usually this occurs when the wind blows the moist air over a cold surface like the ocean.  San Francisco is a place where this type of fog occurs often…almost every day.    Here are three examples.  If you’re thinking that this looks like regular fog, the difference is how it is made.
