Some simple momentum advection effects are considered in a current aligned with the y axis on which there is superimposed a "cross" flow in the x-z plane. The cross flow coupled with horizontal shear ...
Baroclinic Boundary Currents and Long Edge-Waves in Basins with Sloping Shores
Baroclinic Boundary Currents Sloping Shores Long Edge-Waves
2009/3/9
Earlier work on baroclinic “coastal jets” and Kelvin waves in constant-depth basins is extended to basins with sloping shores. Baroclinic coastal jets are again found to be set up by an inflow or outf...

Eastern Boundary Currents Coastal Upwelling
2009/2/8
The adjustment of the eastern coastal zone of an inviscid ocean with vertical walls to a change in wind conditions occurs in two stages. After the propagation of a Kelvin wave across the forced region...

A two-layered ventilated thermocline model is matched with inertial western boundary currents in the southern part of the western boundary region. For general cases the western boundary currents break...
Countergradient vorticity Flux Generated in Continental Boundary Currents
Continental Boundary Currents Countergradient vorticity Flux
2008/12/24
It is suggested that the inshore shear of continental boundary flows like the Florida Current can be accounted for by a countergradient vorticity flux, rather than by lateral diffusion to the shore. T...

2008/12/24
A constant potential vorticity model is used to investigate the relation between the properties of an equatorward-directed western boundary current and the formation of the Equatorial Undercurrent (EU...
