Dynamics of Frontal Intrusions and Their Effects on a Mediterranean Salt Lens
Abstract
The goals were parameterisation of the structure, amplitude, and mixing rate of finite-amplitude lateral intrusions. These occur at most oceanic fronts, including the Gulf Stream, and drive cross-frontal mixing. The highly structured quasi-horizontal sound speed perturbations may strongly affect acoustic propagation across such fronts. Specific objectives were (1) To understand the role of vertical mixing of salt, heat, mass, and momentum in driving lateral intrusions. (2) To predict the scale, structure, and magnitude of finite-amplitude intrusive features in terms of mesoscale gradients. (3) To predict the rate of lateral transport of salt, heat, and momentum caused by intrusive mixing at oceanic fronts.
