Title: The Høvsøre tall wind profile experiment - a description
Abstract: 6 Abstract. We present an analysis of data from a nearly one-year measurement 7 campaign performed at Hovsore, Denmark. Hovsore is a coastal farmland area, where 8 the terrain is flat. Within the easterly sector upstream of the site, the terrain is 9 nearly homogenous. This topography and conditions provide a good basis for the 10 analysis of vertical wind speed profiles under a wide range of atmospheric stability, 11 turbulence, and forcing conditions. One of the objectives of the campaign was to 12 serve as a benchmark for flow over flat terrain models. 13 The observations consist of combined wind lidar and sonic anemometer mea- 14 surements at a meteorological mast. The sonic measurements cover the first 100 m 15 and the wind lidar started measuring at 100 m every 50 m in the vertical. Results 16 of the analysis of the observations of the horizontal wind speed components in the 17 range 10-1200 m and surface turbulence fluxes are illustrated in detail combined 18 with forcing conditions derived from mesoscale model simulations. 19 Ten different cases are here presented. The observed wind profiles approach well 20 the simulated gradient and geostrophic winds close to the simulated boundary-layer 21 height during both barotropic and baroclinic conditions, respectively, except for a 22 low-level jet case as expected. The simulated winds are also presented for complete- 23 ness and show good agreement with the measurements, generally underpredicting 24 the turning of the wind in both barotropic and baroclinic cases. 25
