N2 - For wind resource assessment, the wind industry is increasingly relying on Computational Fluid Dynamics (CFD) models that focus primarily on modeling the airflow in a neutrally stratified surface layer. So far, physical processes that are specific to the atmospheric boundary layer (ABL), for example the Coriolis force, buoyancy forces and heat transport, are mostly ignored in state-of-the-art CFD models. In order to decrease the uncertainty of wind resource assessment, especially in complex terrain, the effect of thermal stratification on the ABL should be included in such models.<br/>The present work examines the influence of stability on the whole ABL using the modified in-house CFD code (DTU Wind Energy) EllipSys3D. Typical diurnal cycles are simulated and compared against previous simulations and measurements from the GABLS II model intercomparison [6].
