SURFACE CURRENTS DUE TO A SUBMERGED DISTURBANCE IN A STRATIFIED OCEAN
2007
Wong, K. K.
Surface currents due to a submerged two-dimensional disturbance of simple harmonic time dependency in a stratified ocean were determined analytically. It was found that the current is a consequence of the formation and propagation of interfacial waves at the thermocline. For large distances from the source of disturbance, the interfacial waves form a regular train of outgoing waves having a definite amplitude and wave number. The surface current also possesses these characteristics. The asymptotic wave number of the surface current is the wave number of free waves at the thermocline.
