orographic lifting - Ascending air flow caused by mountains. Mechanisms that produce the lifting fall into two broad categories: 1) the upward deflection of horizontal larger-scale flow by the orography acting as an obstacle or barrier; or 2) the ...
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.
Orographic Lifting
Same as Upslope Flow; occurs when air is forced to rise and cool due to terrain features such as hills or mountains. If the cooling is sufficient, water vapor condenses into clouds. Additional cooling results in rain or snow.
Orographic lifting The forced rising of air up the slopes of a hill or mountain.
Outgassing Release of gasses to the atmosphere from hot, molten rock during volcanic activity; thought to be the origin of most atmospheric gases.
Orographic Lifting- The upward flowing of air caused by rising terrain, such as a mountain range.
Overrunning- The flow of warm air over cold air in advance of a warm front.
**Orographic Lifting**
Forced aloft the rising air cools by expansion and clouds result as we often see along the Blue Mountains north of the Lehigh Valley.
orographic cloud"Mountain clouds produced by orographic lifting of moist air to saturation.
UPRUpperUpslope FlowSame as Orographic Lifting; air that flows toward higher terrain, and hence is forced to rise.
stable and unstable atmospheric conditions: If a parcel of air is moved upward due to local convergence, convection, orographic lifting, ...
This refers to air which undergoes orographic lifting. Most often, this is in the context of winds such as the chinook or the föhn, which undergo lifting by mountain ranges before descending and warming on the lee side.
Large Cumulonimbus (Cb) clouds are produced with these processes; each cell lasting at least half-an-hour, and depending upon external forcing agents (e.g. coastal convergence, synoptic troughs, orographic lifting), ...
