Zonda is a dry wind (often carrying dust) which comes from the polar maritime air, warmed by descent from the crest, which is some 6,000 m (18,000 ft) above sea level. It may exceed a velocity of 40 km/h (25 mph).
While this type of föhn wind may occur over most central parts of western Argentina, its effects are more impressive in La Rioja, San Juan, and northern Mendoza provinces, because the mountain barrier (the Andes) is higher, while to the north the Puna plateau dissipates these winds.
