Abstract:

This award supported preliminary simulations necessary to aid in the planning stages of the Scalable Lateral Mixing and Coherent Turbulence DRI. The PI performed a series of simulations using a high-resolution model of mesoscale stirring of submesoscale features. In particular, the model used a series of baroclinically unstable mean flows and stratification profiles, relevant to a planned tracer release experiment, to generate an active mesoscale eddy field. The simulation also included a three-dimensional tracer forced by mean lateral gradients. The results indicate that mesoscale stirring can generate ample vertical as well as horizontal structure in the steady-state tracer. The structure is sufficient to explain observed T-S finescale measurements in some locations.
