Slope windstorm

From Glossary of Meteorology



slope windstorm

(Also called downslope windstorm.) Occurs when strong synoptic-scale winds blow over a mountain ridge top, where the winds are trapped below a strong temperature inversion located at an altitude just above the ridge top.

The resulting fall winds on the lee side of the ridge are trapped close to the surface and can destroy buildings and blow down trees.
