Downslope Vs Upslope Winds Weatherbug In summary, downslope winds involve air descending from higher to lower elevations, leading to warming and drying conditions, while upslope winds involve air ascending from lower to higher elevations, resulting in cooling and potentially wetter conditions. Stronger than expected upslope flow can produce higher amounts of precipitation. downslope flow is air moving over terrain such that it flows from a higher to a lower elevation.
Upslope Vs Downslope Winds Weatherbug To explain what's happening, let's take a look at the difference between upslope and downslope flow. 2.1 introduction versal of wind direction twice per day. as a rule, upslope, up valley and plain to mountain flows occur during daytime and downslope, down valley and mountai are also called thermally driven winds. horizontal temperature differences develop daily in complex terrain when cold or warm boundary layers. They are shallower than anabatic winds, mainly because there is less turbulence and upward motion. as the shallow layer of cold air moves downslope, it converges into small valleys and gullies. When winds go up the front side of a mountain, or windward side, they are called upslope winds. when winds go down the backside, or leeward side, they are called downslope winds.

When winds go up the front side of a mountain, or windward side, they are called upslope winds. when winds go down the backside, or leeward side, they are called downslope winds. Slope winds are gravity or buoyancy circulations following the dip of the underlying slope and caused by differences in temperature between air heated or cooled over the mountain slopes and air at the same altitude over the valley center. Begin with an illustrative example: nocturnal slope flow, or katabatic flow (katabatic is a general term for downslope wind; the upslope counterpart is anabatic) consider some height z relative to sea level. Upslope winds start earlier in the day and are relatively weak, while upvalley winds lag behind upslope winds by several hours and are relatively strong. downslope and downvalley winds are caused by the exact opposite mechanism, namely radiational cooling at night. There are multiple different spatial and temporal scales at which the wind moves within the atmosphere, ranging from microscale processes such as how wind can channel between buildings on campus, to global scale processes that govern the jet streams.
