DYNAMICAL OCEANOGRAPHY
Summary
In a barotropic channel model without topography and with only lateral friction, the zonal transport scales with 1/A H where A H is the
lateral viscosity.
The presence of bottom topography substantially decreases the zonal
transport because the topography exerts a force (‘bottom form stress’)
on the overlying water. This force F s is given by
F s = −
p∇h b d
2 x
where p is the pressure and h b is the bottom shape.
Stratification and bottom topography can act together to cause flows to
deviate from being along geostrophic contours; this combined effect
is the JEBAR effect.
Eddies are important in the region of the Antarctic Circumpolar Current to transfer momentum downward in the water column through an
interfacial form stress.
