Adiabatic heating: as air rises and cools within the windward side of a mountain range, it undergoes a course of action known as adiabatic cooling. Conversely, when air descends to the leeward aspect, it encounters adiabatic heating.

Mechanics of atmospheric stress: the motion of air from higher-strain areas to small-pressure locations performs a role inside the Foehn result. As air rises within the windward aspect, it moves from a superior-tension area into a reduced-pressure region at higher altitudes.
