| Summary: | 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. === Graduation date: 1980
