The baroclinic instability of a frontal mean state is investigated using the WK.BJ approximation. T?e !esults are compared with numerical calculations performed on the sa~e mean state. E~cellent a~eement ( withm 5%) is found for jets whose half-width is as small as a Rossby radius of deformation. For Jets 20% broader, the agreement is almost perfect.
