A valley exit jet is a strong, down-valley, elevated air current that emerges above the intersection of the valley and its adjacent plain. These winds frequently reach a maximum of 20m/s (45mph) at a height of 40-200m above the ground. Surface winds below the jet may sway vegetation but are significantly weaker.

A valley exit jet is a strong, down-valley, elevated air current that emerges above the intersection of the valley and its adjacent plain. These winds frequently reach a maximum of 20m/s (45mph) at a height of 40-200m above the ground. Surface winds below the jet may sway vegetation but are significantly weaker. The presence of these strong nighttime down-valley air flows has been documented at the mouth of many Alpine valleys which merge with basins, such as the Inn Valley of Austria, where the jet is strong enough to be heard at the ground. In the United States, exit jet signatures have been observed at the North Fork of the Gunnison River at Paonia, Colorado, the exit of South Boulder Creek south of Boulder, Colorado and the mouth of Spanish Fork Canyon, Utah.
