Abstract : The relationship between vertical motion at the top of the boundary layer, geostrophic vorticity in the boundary layer and divergence in the boundary layer are examined in the study. The equation of motion and the continuity equation are applied to a homogeneous barotropic atmosphere using a numerical model in the study. The solutions reveal that the boundary layer is stable for very large values of Ro in the case of positive vorticity and becomes unstable at Ro = 1.0 in the case of negative vorticity. A difference in behavior is found between cases of anticyclonic and cyclonic shear. The magnitude of the vertical velocity is greater and the boundary is thicker for anticyclonic than for cyclonic shear systems of equivalent strength. (Author)
