The meridional component of the earth's rotation is often neglected in
geophysical contexts. This is referred to as the `traditional approximation'
and is justified by the typically small vertical velocity and aspect ratio of
such problems. Ocean fronts are regions of strong horizontal buoyancy gradient
and are associated with strong vertical transport of tracers and nutrients.
Given these comparatively large vertical velocities, non-traditional rotation
may play a role in governing frontal dynamics.
Here the effects of non-traditional rotation on a front in turbulent thermal
wind balance are considered using an asymptotic approach. Solutions are
presented for a general horizontal buoyancy profile and examined in the simple
case of a straight front. Non-traditional effects are found to depend strongly
on the direction of the front and may lead to the generation of jets and the
modification of the frontal circulation and vertical transport
