An anabatic wind, from the Greek anabatos, verbal of anabainein meaning "moving upward", is a warm wind which blows up a steep slope or mountain side, driven by heating of the slope through insolation. [1] [2] It is also known as upslope flow. These winds typically occur during the daytime in calm sunny weather.
Diurnal wind system variation in the Appalachian mountain range. Mountain and valley breezes form through a process similar to sea and land breezes. During the day, the sun heats up mountain air rapidly while the valley remains relatively cooler. Convection causes it to rise, causing a valley breeze. At night, the process is reversed.
For instance, winds such as the föhn and chinook are rain shadow winds where air driven upslope on the windward side of a mountain range drops its moisture and descends leeward drier and warmer. Examples of true katabatic winds include the bora in the Adriatic , the Bohemian Wind or Böhmwind in the Ore Mountains , the Santa Ana in southern ...
anabatic wind A wind that blows upslope from the low elevations of a valley to the higher elevations of surrounding hills or mountains as the result of daytime surface heating in the valley, usually at speeds of 12 knots (22 km/h; 14 mph) or less but occasionally at much higher speeds.

Winds are part of Earth's atmospheric circulation. The westerlies (blue) and trade winds (yellow and brown) Global surface wind vector flow lines colored by wind speed from June 1, 2011 to October 31, 2011. In meteorology, prevailing wind in a region of the Earth's surface is a surface wind that blows predominantly from a particular direction ...
Santa Ana winds and, their Bay Area cousin, the Diablo winds occur when air from a region of high pressure over the dry Great Basin region of the U.S. flows westward toward lower pressure located ...
Winds of this type are also called "snow-eaters" for their ability to make snow and ice melt or sublimate rapidly. This is a result not only of the warmth of Foehn air, but also its low relative humidity. Accordingly, Foehn winds are known to contribute to the disintegration of ice shelves in the polar regions.
