Wind profiles in atmospheric boundary layer

Abstract: We propose an analytical algebraic model of a turbulent boundary layer based on the equations for vortex flow, which take longitudinal motion and rotation of vortex tubes into account. In case of plane turbulent flows this model allows one to calculate the mean velocity distributions in boundary layers under various conditions. In particular, we verify proposed model by comparison with the experimental profiles measured in the wind tunnel as well as by fitting of experimental low-level jets profiles measured in atmospheric boundary layer. In all considered cases the calculated model profiles demonstrate good agreement with experimental data.
