Abstract

The stability of the Ekman thermally stratified boundary layer simulating the atmospheric boundary layer is studied theoretically. The system of thermohydrodynamic equations is solved in the Boussinesq approximation. Two mechanisms of development of the vortex structures, namely, thermal and dynamic, as well as their interaction, are investigated. It is shown that a sharp boundary on which the flow characteristics change qualitatively exists between various domains of the parameters corresponding to thermal and dynamic instabilities.
