From Glossary of Meteorology
- The mountain wind of a canyon, that is, the nighttime down-canyon flow of air caused by cooling at the canyon walls.
Because of the steepness of the slopes, canyon winds can be very strong.
- (Or gorge wind.) Any wind modified by being forced to flow through a canyon or gorge, especially by a strong pressure gradient as is the case with mountain-gap winds.
The easterly Wasatch winds of Utah are examples. The speed of canyon winds may be increased as a jet-effect wind (
see also gap wind), and their direction is rigidly controlled by the topography.
Same as Wasatch winds.
