The object of this study is to explain the occurrence of relatively large amplitude inertial motion observed at great depths in the ocean. An arbitrarily stratified, β-plane model is considered consisting of a viscous boundary layer at the surface and an inviscid interior. The forcing due to a wind stress produces Ekman suction in the boundary layer which in turn drives the interior. Ray theory is then used to describe the propagation of disturbances in the boundary layer down into the interior....
