Upwind effect

From Glossary of Meteorology



upwind effect[edit | edit source]

The effect of an orographic barrier in producing orographic precipitation to the windward of the base of the barrier as a result of orographic lifting mechanisms that produce rising motion upwind of the barrier.

Orographic blocking of moist, stable approach flow is an example of one such mechanism.


  1. The obstructing, on a large scale, of the normal west-to-east progress of migratory cyclones and anticyclones.
