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.
The wind then backs quickly through northerly to north-westerly as its temperature rises. This is the berg wind phase of the coastal low. The wind then changes abruptly to a strong, cold, south or south-westerly wind (called a “buster” if the change in wind speed is greater than 35 km/h).
Berg wind, a seasonal katabatic wind blowing down the Great Escarpment from the high central plateau to the coast in South Africa.; Cape Doctor, often persistent and dry south-easterly wind that blows on the South African coast from spring to late summer (September to March in the southern hemisphere).
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 Anas are katabatic winds (Greek for "flowing downhill") arising in higher altitudes and blowing down towards sea level. [7] The National Weather Service defines Santa Ana winds as "a weather condition [in southern California] in which strong, hot, dust-bearing winds descend to the Pacific Coast around Los Angeles from inland desert regions".
Wind chill makes it feel much colder than it really is, so it's been described as a "feels-like" number. If the temperature is 0 degrees and the wind is blowing at 15 mph, the wind chill is 19 ...

Endocrinologists share uncommon symptoms of diabetes that may indicate type 1, type 2, or prediabetes. Some signs include infections and dry skin.
