> *Abstract: *  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.
