Synergistic Observations of Rossby Waves
Rossby waves are an important part of the ocean's response to changes in atmospheric stimuli, and provide a mechanism by which the west of ocean basins learns of changes in the east. In the past decade many papers have discussed their sea surface height signal in the altimetric record, showing that Rossby waves are common in all ocean basins and drawing attention to the discrepancy between obse...
متن کاملTrapping Rossby Waves
Waves associated to large scale oceanic motions are gravity waves (Poincaré waves which disperse fast) and quasigeostrophic waves (Rossby waves). In this Note, we show by semiclassical arguments, that Rossby waves can be trapped and we characterize the corresponding initial conditions.
متن کاملRossby waves: synergy in action.
Rossby waves are an important phenomenon, linking processes in the west of ocean basins with forcing that occurred earlier in the east. We show evidence for such features in satellite-derived datasets of sea-surface height, temperature and ocean colour, using a section of the south Indian Ocean as an example. We discuss the possible mechanisms for an effect on chlorophyll, and we investigate th...
متن کاملThe Three-Dimensional Structure of Breaking Rossby Waves in the Polar Wintertime Stratosphere
The three-dimensional nature of breaking Rossby waves in the polar wintertime stratosphere is studied using an idealized global primitive equation model. The model is initialized with a well-formed polar vortex, characterized by a latitudinal band of steep potential vorticity (PV) gradients. Planetary-scale Rossby waves are generated by varying the topography of the bottom boundary, correspondi...
متن کاملMomentum Flux and Flux Divergence of Gravity Waves in Directional Shear Flows over Three-Dimensional Mountains
Linear mountain wave theory is used to derive the general formulas of the gravity wave momentum flux (WMF) and its vertical divergence that develop in directionally sheared flows with constant vertical shear. Height variations of theWMF and its vertical divergence are studied for a circular bell-shapedmountain. The results show that the magnitude of the WMF decreases with height owing to variab...
