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.
