A Model for Heat Patch in the Boundary Layer of the Geostrophic Flow

E. M. Dobryshman and E. A. Kokoshinskii

A hydrodynamic model is considered for a disturbance of wind field structure of the boundary layer in the geostrophic flow running onto a warmer underlying surface. It is shown that the breeze effect causes the lowering (or heightening) of streamlines in a narrow area of sharp changes in curvature of horizontal profile of temperature disturbance. The technique by A.A. Dorodnitsyn for solution of parabolic equation set is illustrated by an example of a streamline and vertical velocity calculation over a wide “warm” river. A scheme is presented explaining the breeze effect on the boundary layer structure.
