Frontal instability and energy dissipation in submesoscale fronts

Universität Rostock, 2020

Abstract: Theory and numerical simulations suggested that submesoscale fronts and filaments are subject to various types of instabilities, providing a potentially important pathway for the downscale transport and dissipation of mesoscale kinetic energy in the ocean. Based on the observational data collected from the Benguela upwelling system, this thesis, for the first time, provided direct evidence for the detailed structure of turbulence triggered by forced/unforced/inertial symmetric instability and marginal shear instability in submesoscale fronts.
