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.
Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...
Prevailing winds are strongly influenced by Earth's overall atmospheric circulation, in addition to smaller-scale and shorter-lived weather phenomena. In meteorology, prevailing wind in a region of the Earth's surface is a surface wind that blows predominantly from a particular direction. The dominant winds are the trends in direction of wind ...
The mountain breezes then generate anabatic winds which also rise. dynamic forcing when air is stable lower down, and circulation is blocked by the mountain, but the air is unstable at higher altitude. In this case general circulation is forced above this blocking layer and can reach the convective layer.
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 ...
A katabatic wind (named from Ancient Greek κατάβασις 'descent') is a downslope wind caused by the flow of an elevated, high-density air mass into a lower-density air mass below under the force of gravity.
A combination of geographic factors make Paro – and much of Bhutan – visually stunning. They also make flying in and out of Paro a highly specialized skill.
