An investigation of the highly turbulent region in the lee of a two-dimensional mountain ridge was carried out in the Meteorological Wind Tunnel of the U.S. EPA's Fluid Modeling Facility. This highly turbulent region was found to consist of a large semi-permanent eddy. Smoke visualization and hot film anemometry measurements showed that the cavity size and shape are minimally affected by the thickness and turbulence intensity of the approach boundary layer flow. In addition, the cavity size and shape were not found to be affected by the detailed shape of the ridge, but were strongly dependent upon the upwind terrain and the gross features (angles) of the downslope.
