In this note, we derive from the resistance law of Rossby number similarity theory the expressions for the drag coefficient and the deviation angle for strongly unstable and strongly stable stratifications. The extension of the applicability of the resistance laws to inhomogeneous terrain is discuss
We present analytical and numerical calculations of the effective roughness length (ERL) over a flat surface with varying roughness elements, for use in large-scale models. It is shown that ERL is mostly determined by the roughest elements present inside the averaging domain and that, more surprisin
