<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>
