A fog that is formed when air is forced up the side of the mountain and thus cools to the dewpoint temperature resulting in saturation and the development of a cloud.

Fog that forms in humid air flowing uphill.

Fog which is formed on the windward slopes of high ground by the forced uplift of stable , moist air till saturation is reached by adiabatic expansion.

Fog that is created when air moves up a mountain slope.

Fog which forms when moist air flows up the windward side of high ground. The air is cooled below its dew point by adiabatic expansion during lifting.

A type of fog formed when air flows upward over rising terrain and is, consequently, adiabatically cooled to or below its dewpoint.

Fog produced by air flowing over topographic barriers. As the air is forced to rise, it is cooled by adiabatic expansion. Upslope fog is most common on the windward slopes of hills or mountains.

Fog formed as moist, stable air flows upward over a topographic barrier.

Fog that forms when warm, moist surface air is forced up a slope by the wind. It is adiabatically cooled to below its initial dew point, which means the air cools by expansion as it rises. It forms best where there is a gradual slope, and it can become quite deep, requiring considerable time to dissipate.
