Abstract
A numerical study is made of the interaction between convective and an accelerating background flow in the atmospheric boundary layer. The large difference between the horizontal scales of these processes makes it possible to divide the initial three-dimensional system of equations into two simpler, two-dimensional interacting subsystems for the background flow and the convective movements, respectively. This makes the problem amenable to numerical solution and makes it possible to describe in a differential model the essential traits of the convective boundary layer structure, which is characterized by the presence of a mixing layer bounded from above by a fairly stable stratified layer (in particular, by an inversion).
