Here, we opt for a model of intermediate complexity which allows in depth analysis of the stable boundary layer with coupling to vegetation and soil through a surface energy budget. The model is used to investigate the nonlinear feedbacks between the flow and the ground. By benchmarking to selected ensemble observations from the Cabauw site in the Netherlands, we aim to capture the basic 10-year climatology of the site for varying wind speed classes.
The goal is to find critical dimensionless parameters to predict the transition from the weakly stable to the very stable case. We expect that in addition to mechanical forcing, unknown parameters involving ground properties, will play a role in critical flow transitions.
