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.
The Santa Ana winds of southern California, including the Sundowner winds of Santa Barbara, are in some ways similar to the Föhn, but originate in dry deserts as a katabatic wind.

The unique conditions of flying in and out of Paro mean that jumbo jets are a no-go. ... “So land is parched and you get all these up drops and get all these anabatic/katabatic winds in the ...
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 ...
In a more general case, several effects may be present and if the synoptic wind is opposed to the anabatic wind, additional convergence occurs at the top of the mountain. [3] It is also possible to create a convergence zone behind the mountain when the synoptic wind can divide and go around it to meet again (ex. Puget Sound Convergence Zone ...
A watch means that conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make ...
Low wind chill numbers are a sign you need to dress for colder conditions. For example, when the wind chill is around 40 degrees below zero, exposed skin can freeze in as little as 10 minutes.
