Upslope Flow
Same as Orographic Lifting; air that flows toward higher terrain, and hence is forced to rise.
Upslope Flow - Air that gradually rises along an elevated plain and consequently cools to the dew point. Occurs when easterly winds prevail and often lead to low clouds, fog and generally steady and light precipitation.
Downslope/Upslope Flow Air that descends down a mountain chain or over sloping terrain (pressurized air moving from high pressure to low pressure), resulting in subsequent drying, and in some cases, ...
The retardation of stable, low-level, forced upslope flow on the windward side of a mountain or mountain barrier; Smith (1979) asserts that "this windward-side slowing is due to the difficulty that the heavy [cold] surface air has in running upslope.
leeside convergence"Region of convergence, often a line, downwind of a mountain or mountain ridge during fair-weather daytime conditions that are favorable for the formation of thermally forced upslope flow and deep convective mixing.
Valley breeze A shallow, upslope flow of air that develops during daylight hours within mountain valleys.
Vapor pressure The portion of the total air pressure exerted by the water vapor component of air.
Orographic LiftingSame 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.
