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.
Buran (a wind which blows across eastern Asia. It is also known as Purga when over the tundra); Karakaze (strong cold mountain wind from Gunma Prefecture in Japan); East Asian Monsoon, known in Korea as jangma (), and in Japan as tsuyu (梅雨) when advancing northwards in the spring and shurin (秋霖) when retreating southwards in autumn.
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.

A katabatic wind (named from Ancient Greek κατάβασις 'descent') carries high-density air from a higher elevation down a slope under the force of gravity. Such winds are sometimes also called fall winds ; the spelling catabatic winds [ 1 ] is also used.
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.
Prediabetes is a condition that occurs when blood sugar levels are above normal but not quite yet a diagnosable disease, according to Marjorie Nolan Cohn, a registered dietitian and clinical ...
