## Abstract Velocity profiles observed in near neutral conditions at the Risø 125 m tower are presented. The upwind terrain contains, depending on wind direction, either one or two distinct changes in surface roughness. Comparisons are made between the observed profiles and those predicted using m

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 A new study has been made of the Risø profiles with the following conclusions: roughness lengths determined from neutral wind profiles selected by gradient Richardson number are biased towards high roughness lengths. Selecting the profiles by using a bulk Richardson number criterion yie
