Abstract: The zonal modulation of baroclinic disturbances is studied in a quasigeostrophic two-layer periodic channel. The system is relaxed toward an unstable state with a uniform flow in each layer. For small criticality, two ...

Abstract: The effect of a simple representation of the Hadley circulation on the propagation and nonlinear reflection of planetary-scale Rossby waves in the winter hemisphere is investigated numerically in a single-layer shallow-water ...

Abstract: Using a global, one-layer shallow water model, the response of a westerly flow to a localized mountain is investigated. A steady, linear response at small mountain heights successively gives way first to a steady flow in ...
