Abstract: A pseudocritical level is defined as a region where the wave phase speed c equals the zonal basic flow velocity U and, additionally, the background potential vorticity gradient vanishes. In this study Rossby wave propagation ...

Abstract: Inertia–gravity waves (IGWs) play an essential role in the terrestrial atmospheric dynamics as they can lead to energy and momentum flux when propagating upward. An open question is to what extent IGWs contribute to the ...

Abstract: This study examines quasigeostrophic Rossby eigenmodes of homogeneous as well as stratified oceans. Analytical studies of Rossby basin modes are usually done by using simple basin geometries. Simple means that solutions ...
