We have measured profiles of an onshore wind 200 m upwind and 200 m downwind from an abruptly rising shore using a remote-sensing Doppler lidar anemometer. Data were taken at heights between 4.7 and 66.5 m above sea level. Results show that the onshore velocity vector slopes upward 16.6 to 9.6", the
## Abstract The response of the boundary layer wind profile and the surface shear to a large step change in surface roughness is predicted by three calculation methods and the predictions are compared with measurements by Bradley. The first method, which assumes that local equilibrium exists everyw
