Types of fog

Advection fog: Advection fog occurs when moist air passes over a cool surface by advection (wind) and is cooled. Advection means a horizontal movement of air. Advection fog is fog produced when air that is warmer and moister than the ground surface moves over the ground surface.

Fog consists of visible cloud water droplets or ice crystals suspended in the air at or near the Earth's surface.[1] Fog can be considered a type of low-lying cloud and is heavily influenced by nearby bodies of water, topography, and wind conditions.

radiation fog. fog produced by the nocturnal cooling of the surface boundary layer to a temperature at which its content of water vapor condenses.

Upslope fog definition is - fog produced by the flow of moist air along upward sloping terrain.

Valley Fog. As the Northern Hemisphere transitions from summer to fall, weather conditions become more favorable for the development of late night and early morning valley fog.
