Highly resolved large-eddy simulations of flow in the nighttime atmospheric boundary layer allow an improved understanding of physical processes and its impact on wind, temperature and turbulent eddies in the atmosphere. This highly resolved large-eddy simulations are essential for a detailed investigation of the impact of the rotating system of a wind turbine on its wake and the wake interaction with the atmosphere. The goals are to study the interaction of the Coriolis force with the vortex imposed on the atmosphere by the rotating system of a wind turbine to improve its physical understanding and in addition its impact on a downwind turbines’ performance. This is particularly important in complex terrain considering the additional topography-induced forces acting on the boundary-layer flow.
