PARAMETERIZATION OF CONVECTIVE AND STABLE INTERNAL BOUNDARY-LAYERS INTO MASS CONSISTENT MODELS

Feasibility studies for the deployment of wind turbines and for air qu ality analysis in coastal regions require detailed knowledge of wind c limatology in this area. In practice, however, the information availab le is very limited. Thus, the improvement of the physical modelling in the existing relatively simple micrositing models seems to be a good compromise between desired accuracy land reliability) and required com puter resources and expertise. In this work, simple parameterizations of the IBL concept, in a first step due to the effect of a change in s urface roughness and in a second step taking into account a change in surface temperature, have been introduced in a mass consistent model. For the validation of the model, data of wind speed at 10 m height at three locations, from a wind held experiment over a complex topography , were used, showing a satisfactory model improvement.
