The gravity waves (GWs) generated by potential vorticity (PV) anomalies in a rotating
stratified shear flow are examined under the assumptions of constant vertical shear, two-
dimensionality, and unbounded domain. Near a PV anomaly, the associated perturbation is
well modeled by quasigeostrophic theory. This is not the case at large vertical distances,
however, and in particular beyond the two inertial layers that appear above and below the
anomaly; there, the perturbation consists of vertically propagating gravity waves. This …
