Trapping 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 کاملSynergistic 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 کاملCaustics of weak shock waves
The caustics of weak shock waves are studied through matched asymptotic expansions. It is shown that these caustics are thinner and more intense than those of smooth waves with a comparable amplitude. This difference in scalings solves a paradox that would have the caustics of weak shock waves behave linearly, even though linear theory for discontinuous fronts predicts infinite amplitudes near ...
متن کاملRossby waves in ocean circulation*
-It is shown that damped, stat ionary Rossby waves can occur in the ocean superimposed on a steady west to east flow. A model o f wind-driven ocean circulation in a two dimensional homogeneous ocean is constructed in which Rossby waves occur in the northern port ion of the basin. I N T R O D U C T I O N SINCE the work of SmMMEL (1948) it has been recognized that any dynamic theory of wind-drive...
