ABSTRACT:


Stochastic parameterization is employed to capture the effect of wave breaking dissipation and diffusion in a balanced and comprehensive model for wave and current interactions that we recently developed.
The wave/current model, which captures their long-time and large-space interactions is also capable of answering how conservative effects are modified by the presence of wave breaking. Specifically, wave breaking will induce a Reynolds stress type momentum term, which is associated with dissipation, and a diffusion term that results from the enhanced mixing and growth of the planetary boundary layer.
The choice of stochastic parameterization permits the more direct and straightforward insertion of oceanic data, as compared to turbulence closure models.
