Examples of katabatic winds include the downslope valley and mountain breezes, the piteraq winds of Greenland, the Bora in the Adriatic, [2] the Bohemian Wind or Böhmwind in the Ore Mountains, the Santa Ana winds in southern California, the oroshi in Japan, or "the Barber" in New Zealand. [3] Not all downslope winds are katabatic.
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.
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).

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.

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).
