  Analyses of both altimetric data and in-situ measurements reveal patterns of
meridionally-alternating, nearly zonal, coherent jet-like structures in many of
the world ocean basins. In this context, recent Ocean General Circulation Model
(OGCM) simulations that resolve such zonal jet-like features show that they
also propagate, largely in the meridional direction. To investigate such
propagation, a feature that has received scant attention, we consider the
behavior of such jets in a two-layer quasi-geostrophic model on a closed
mid-latitude basin and forced by a double-gyre wind forcing. In this setup, we
find that jets are evident in the baroclinic mode of instantaneous fields, that
they propagate largely in the meridional direction, and that the propagation is
related to an advective mechanism.
