Abstract:
Abstract: An f-plane, quasi-geostrophic, 2 1/2 layer model is
used to examine whether cross-jet transport can be enhanced at depth in a
surface-intensified ocean jet, similar to the Gulf Stream. By using
dynamical systems techniques, we find that cross-jet transport can be
enhanced in the lower layer, but only when the vertical shear
is sufficiently strong. Some preliminary results for
understanding the role of transport barriers in controlling potential
vorticity mixing will also be presented.
