Orographic lift occurs when an air mass is forced from a low elevation to a higher elevation as it moves over rising terrain. [ 1 ] : 162 As the air mass gains altitude it quickly cools down adiabatically , which can raise the relative humidity to 100% and create clouds and, under the right conditions, precipitation .
Ridge lift is generated when the wind blows against a hill, ridge, escarpment or ocean wave, causing the air to rise. In meteorology this is known as orographic lift. The wind creates a region of rising air directly above the slope, which may extend some distance upwards and outwards from its face because the airflow follows the upward contour ...

The lift of the air up the side of the mountain results in adiabatic cooling with altitude, and ultimately condensation and precipitation. In mountainous parts of the world subjected to relatively consistent winds (for example, the trade winds ), a more moist climate usually prevails on the windward side of a mountain than on the leeward ...
Lift is a meteorological phenomenon used as an energy source by soaring aircraft and soaring birds. The most common human application of lift is in sport and recreation. The three air sports that use soaring flight are: gliding, hang gliding and paragliding. Energy can be gained by using rising air from four sources: Thermals (where air rises ...
The interior Chinook is a föhn wind, a rain shadow wind which results from the subsequent adiabatic warming of air which has dropped most of its moisture on windward slopes (orographic lift). As a consequence of the different adiabatic rates of moist and dry air, the air on the leeward slopes becomes warmer than equivalent elevations on the ...
An orographic map of Eastern Siberia from 1875 by Peter Kropotkin. Orography is the study of the topographic relief of mountains, [1] and can more broadly include hills, and any part of a region's elevated terrain. [2] Orography (also known as oreography, orology, or oreology) falls within the broader discipline of geomorphology. [3]
A third source of lift is wind circulation forcing air over a physical barrier such as a mountain (orographic lift). [10] If the air is generally stable, nothing more than lenticular cap clouds will form. However, if the air becomes sufficiently moist and unstable, orographic showers or thunderstorms may appear.
