Open flat terrain; grass, few isolated obstacles. the golden crust restaurantWebThe roughness length is loosely related to the typical height of closely spaced surface obstacles, often called roughness elements (e. g. water waves, trees, buildings, blades of grass). It depends on the distribution as well as the height h c of roughness elements (see figure below), but as a rule of thumb, z 0 ~ 0.1h c. (5.5) the golden cup bookWebRoughness length is a parameter of some vertical wind profile equations that model the horizontal mean wind speed near the ground.
