jet-effect wind

A local wind created by acceleration of the airflow through a gap, constriction, or channel in a mountain range or between ranges.

The acceleration can result from a large-scale pressure gradient, or by Venturi acceleration through a constricting passage. Pressure gradients from large-scale processes can occur when a large- scale anticyclone lies on one side of the barrier, as in the case of canyon or Wasatch winds, or when a cold front impinges on a mountain barrier with a gap in it and the cold air mass forces its way through the gap, as in the case of the tehuantepecer. Other jet-effect winds include the düsenwind, the kossava, and gap winds.
See also mountain-gap wind.
