Orographic
Lifting
Where the flow of air is forced up and over barriers such as
highlands or mountains. Moist air being forced aloft begins to
cool, consequently condensation forms, and rain or snow begins to
fall. By the time the air reaches the leeward side of the barrier,
it sinks and warms, resulting in decreasing relative humidity,
cessation of precipitation, and the dissipation of clouds. May be
called an orographic uplift.
