| Abstract | An analytical two-layer model consisting of a time-dependent stratified boundary layer topped by stratified free flow is developed in order to study atmospheric boundary layer production of vertical motion. To avoid use of a constant eddy viscosity, the boundary layer equations are layer-integrated over a fixed depth, and surface stress is parameterized using a linearized drag law. For flows driven by periodic, differential surface heating, it is found that the influence of accelerations, stratification, and friction are to concentrate the maximum convergence near a preferred latitude. The preferred horizontal length scale for boundary layer production of vertical motion increases with boundary layer stratification and decreases with distance from the preferred latitude. |
