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 .
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 ...
Tectonic–climatic interaction is the interrelationship between tectonic processes and the climate system. The tectonic processes in question include orogenesis, volcanism, and erosion, while relevant climatic processes include atmospheric circulation, orographic lift, monsoon circulation and the rain shadow effect.
The mountain range is widely believed to serve as a typhoon barrier for Luzon. However, it is only truly effective for Cagayan Valley where wind exposure and rainfall brought by the typhoon are both reduced. For the rest of Luzon along its western slopes such as in Metro Manila, rainfall is actually enhanced by orographic lifting. [3] [4]

Mechanisms of producing precipitation include convective, stratiform, [10] and orographic rainfall. [11] Convective processes involve strong vertical motions that can cause the overturning of the atmosphere in that location within an hour and cause heavy precipitation, [ 12 ] while stratiform processes involve weaker upward motions and less ...
This is a process in meteorology we call “orographic lift.” When a moist airmass, in this case, Helene, travels into mountainous areas, the terrain forces the air upward.
While passing over the Philippines, Thelma's interaction with the high terrain of some of the islands resulted in torrential rainfall. Through the process of orographic lift, much of the Visayas received 150 mm (6 in) of rain; however, on Leyte Island there was a localized downpour that brought totals to 580.5 mm (22.85 in). With the majority ...
