Internal Wave Driven Mixing and Transport in the Coastal Ocean

Abstract

The long-term goal of this research is to develop improved parameterizations of internal wave driven mixing in global circulation models where such small-scale processes are not resolved (i.e. occur as subgrid-scale processes). The main objectives are: (1) to perform a series of high-resolution "numerical" microstructure profile studies using representative field scale flows in the coastal ocean to investigate the relationship between relevant length scales and time scales for mixing of both momentum and scalar (density); (2) to formulate parameterizations for diapycnal (irreversible) mixing driven by internal waves; and (3) to explain the fate of nonlinear internal waves (NLIWs) that propagate into shallower seas as a result of the interaction process and determine whether they contribute significantly to mixing and transport.
