Abstract: The two major approaches to understanding plane parallel shear instability?the counterpropagating Rossby wave (CRW) and overreflection (OR) approaches?illuminate very different fundamental aspects. This work examines how ...

Abstract: he North Atlantic jet stream during winter 2010 was unusually zonal, so the typically separated Atlantic and African jets were merged into one zonal jet. Moreover, the latitude?height structure and temporal variability of ...

Abstract: Motivated by the success of potential vorticity (PV) thinking for Rossby waves and related shear flow phenomena, this work develops a buoyancy?vorticity formulation of gravity waves in stratified shear flow, for which the ...
