|Abstract: ||We model the effects of an internal wave on the structure of the oceanic subsurface bubble layer,
generated by breaking surface waves.We consider two situations: when breaking is caused either by
a strong sustained wind or by the direct interaction of surface waves with an internal wave. We find
that the effects are twofold; bubbles are driven by the internal wave field and the injection of bubbles
into the water is enhanced in downwelling areas behind the crests of the internal wave. We use an
uncoupled problem formulation, substituting the solution for an internal wave in a two-layer fluid
model into the equations describing the bubble dynamics. The latter equations are solved
numerically, showing structure formation in the bubble layer for each of the two cases, when one of
the aforementioned mechanisms dominates the other. © 2010 American Institute of Physics.|
