An Evaluation of Stokes Velocities and Inertia Currents Generated by Deep-Water Surface Gravity Waves.

A system for evaluating the horizontal motions induced by deep-water surface gravity waves is developed for a three-dimensional rotating ocean. The effects of secondary vorticity as well as the associated volume transports, variations with depth, depths of influence and vertical velocities due to ho...

Description
Summary:A system for evaluating the horizontal motions induced by deep-water surface gravity waves is developed for a three-dimensional rotating ocean. The effects of secondary vorticity as well as the associated volume transports, variations with depth, depths of influence and vertical velocities due to horizontal convergences and divergences are considered. The application of this system to hindcasted, directional-frequency spectra of wave elevation in the North Atlantic shows that when waves are in a transient state, a Stokes current is generated that is capable of explaining a number of features of oceanic current variability. On longer time scales, a rotary current is generated that is shown to be capable of acting as a possible random source for simulating observations of inertial oscillations in the open sea. (Author)
