A parameterization of momentum roughness length and displacement height for a wide range ofcanopy densities
momentum roughness length canopy densities
2009/6/8
Values of the momentum roughness length, z0, and displacement height, d, derived from wind profiles and momentum flux measurements, are selected from the literature for a variety of sparse canopies. T...
Wind Stress and Roughness Length over Breaking Waves
Wind Stress Roughness Length Breaking Waves
2009/3/7
The effects of surface wave breaking on the adjacent atmospheric boundary layer are examined. It is argued that the transition from aerodynamically smooth to rough flow in a neutral atmosphere corresp...
Effective Roughness Length for Turbulent Flow over a Wavy Surface
Roughness Length Turbulent Flow Wavy Surface
2009/1/4
A two-equation turbulence model is used to calculate the effective roughness length for two-dimensional turbulent flow over small amplitude, wavy surface topography. The governing equations are solved...
Simulation of the Wind-Forced Near-Surface Circulation in Knight Inlet: A Parameterization of the Roughness Length
Wind-Forced Near-Surface Circulation Knight Inlet Roughness Length
2008/7/11
Month-long observations of along-channel velocity made close to the surface of Knight Inlet are used with a numerical model to estimate the roughness length z0 on the water side of the air–sea interfa...
