etesian wind

etesian wind

      remarkably steady southbound drift of the lower atmosphere over the eastern Mediterranean and adjacent lands in summer. From about mid-May to mid-September, it generally dominates the Adriatic, Ionian, and Aegean seas and the adjacent countries.

      The name (from Greek etos, “year”) is suggestive of the wind's regular recurrence. The wind is of such significance to human activities that the ancient Greeks announced its expected beginning in the marketplaces. An extreme example of its constancy is at Cairo, where July winds blow from the northwest, north, or northeast 98 percent of the time.

      The etesian wind, which reaches maximum intensity in the early afternoon and may cease during the night, is part of the general inflow of air toward a low-pressure area usually centred over northwestern India in summer. The wind is actually a dry monsoon wind since it is rainless and not accompanied by high relative humidity. It is not replaced in winter by a steady drift from the opposite direction, and thus the term monsoon is not generally used to describe this wind.

      Similar wind regimes and climates, called etesian climates and characterized by dry summers and rainy winters, are present in California, Chile, South Africa, and southwestern Australia.
