Dynamics of and Characteristics of Numerical Models of Weakly Nonlinear Flows

Abstract

LONG-TERM GOAL. There are two long-term goals of this research program. First, we wish to explore and understand the role of mesoscale and sub-mesoscale currents in ocean circulation and the affect of these flows upon nutrients, plankton, and other nearly passive tracers. This exploration examines mesoscale flows and dynamics both locally and regionally. Within important nonlinear flows, sub-mesoscale features develop in the form of fronts and small vortices where relative vorticity is comparable to the Coriolis parameter. These can be trapped to topographic features, generated by small scale stationary atmospheric phenomena, or freely propagating. The second goal is to develop and apply the best available numerical models and assimilation methodology for regional modeling.
