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.
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).
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".
A piteraq is a cold katabatic wind which originates on the Greenlandic icecap and sweeps down the east coast. The word "piteraq" means "that which attacks you" in the local language. [1] Piteraqs are most common in the autumn and winter. Wind speeds typically reach 50 to 80 m/s (180–288 km/h; 111–178 mph).
Katabatic wind [ edit ] Commonwealth Bay is listed in both the Guinness Book of World Records and the Eighth Edition of the National Geographic Atlas as the windiest place on Earth, with winds regularly exceeding 240 kilometres (150 mi) per hour and an average annual wind speed of 80 kilometres (50 mi) per hour.
The wind takes two different traditional names in areas of Italy and Croatia depending on associated meteorological conditions: the "light bora" (Italian: bora chiara) is a bora in the presence of anticyclone clear skies, whereas cyclone clouds gathering on the hilltops and moving towards the seaside with rain or snow characterize the "dark ...
The ground loses energy by radiation and the air in contact with it cools down by conduction until sunrise. When this process occurs on mountain slopes, the cooling air becomes denser than the air further afield and sinks downslope producing a katabatic wind. When the cold air reaches a relatively flat area or a valley, it slows down and ...
