Measurements of heat and humidity fluxes in the wake of offshore wind turbines
Eddy-covariance measurements of heat and humidity fluxes at heights of 40 m and 80 m above the sea surface in the wake of the alpha ventus wind farm in the North Sea at the FINO1 platform are presented and compared with fluxes estimated using the bulk method, which is generally applicable offshore outside of wake regions. While a clear difference is not found between bulk-estimated and eddy-covariance-derived fluxes in unstable conditions in the wake of the wind farm, a modified heat flux of between −10 W m−2 and −20 W m−2 with respect to the expected open-sea magnitudes is found within the wake during stable stratification at both measurement heights. These results demonstrate the importance of the realistic inclusion of buoyancy in modeling stable wind-farm wakes for offshore conditions and assessing their effect on the efficiency of downstream wind farms, as well as on the local climate.
