Symmetry breaking and nonlinear transformation of two-layer eastward propagating dipoles
Matthew. N. Crowe, Georgi. G. Sutyrin
We study the evolution of eastward propagating dipoles (modons) in a two-layer quasi-geostrophic -plane model using high-resolution numerical simulations. Various combinations o…
Spectral Methods for Coastal-Trapped Waves and Instabilities in a Background Flow
Matthew N. Crowe, Edward R. Johnson
Here we present a numerical method for finding non-hydrostatic coastal-trapped wave and instability solutions to the non-hydrostatic Boussinesq equations in the presence of a backg…
Modon solutions in an N-layer quasi-geostrophic model
Matthew N. Crowe, Edward R. Johnson
Modons, or dipolar vortices, are common and long-lived features of the upper ocean, consisting of a pair of monopolar vortices moving through self-advection. Such structures remain…
The modification of turbulent thermal wind balance by non-traditional effects
Matthew N. Crowe
The meridional component of the earth's rotation is often neglected in geophysical contexts. This is referred to as the `traditional approximation' and is justified by the typicall…
