Abstract

Wind speed was measured near the surface, along a line normal to a single, 50 % porous windbreak. The results for near-neutral atmospheric conditions were strongly dependent on the incidence angle of the wind, a, and slightly dependent on the roughness of the surface. A measure of the shelter effect - the protected distance - was found to decrease faster than cos α. The drag coefficient of the windbreak decreased proportionally with cos α. The effect of increased roughness was to increase the wind speed near the surface in the lee of the windbreak.
