Katabatic Winds

These are winds that carry dense air from a higher elevation to a lower elevation due to gravity. They are known locally as the Santa Ana (southern California), the Mistral (Mediterranean), the Bora (the Adriatic Sea), Oroshi (Japan), Pitaraq (Greenland), and the Williwaw (Tierra del Fuego). The Williwaw and winds traveling over the Antarctic are particularly hazardous, blowing over 100 knots at times.
