<b>Abstract: </b> Topography plays a central role in ocean
dynamics, but our intuition is nevertheless based largely on
flat bottom models. This includes aspects like the
baroclinic modes used for representing vertical structure
and the character of baroclinic instability. A good example
is Rossby waves, whose vertical structure and stability are
both affected by bathymetry. Relatively modest topography
causes the waves to be surface-trapped, which in turn alters
their deformation radius and propagation speed. Rossby waves
are also baroclinically unstable and this too is altered by
bathymetry. If the topographic heights are large enough,
energy is transferred directly to topographically-locked
flows rather than to the most unstable wave found over a
flat bottom. The resulting turbulent flow is also affected
by bathymetry, with the deep flow slaved to topography and
compensated surface eddies. The resulting flows strongly
resemble those in the ocean interior, with westward
propagation at the surface and deep gyres.</div>
