Abstract: A homogenization technique is used to study the change in the frequency of planetary Rossby waves that results from their interaction with a small-scale two-dimensional topography. The frequency change is computed explicitly ...

Abstract: Application of the stability theorems for multilayer quasigeostrophic flows reveals that the three-layer model may be nonlinearly unstable while in linearly subcritical conditions, the instability being then due to explosive ...

Abstract: ecent studies indicate that altimetric observations of the ocean?s mesoscale eddy field reflect the combined influence of surface buoyancy and interior potential vorticity anomalies. The former have a surface-trapped ...

Abstract: 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 ...

Abstract: he gravity waves (GWs) produced by three-dimensional potential vorticity (PV) anomalies are examined under the assumption of constant vertical shear, constant stratification, and unbounded domain. As in the two-dimensional ...
