The forced response of a horizontally infinite ocean on a rotating earth to a transient wind system is investigated. In an equilibrium state, the ocean consists of two homogeneous layers of fluid of finite depth, the fluid in the lower layer being slightly denser than that in the upper. The wind system is periodic in space, and its time-dependence is periodic or is given by a step function....
