Evolution of the Wave Packet in Barotropic Flows
We now are ready to apply the theory developed in Chapter 2 to geophysical fluid dynamics. In this chapter and the next three chapters, we consider the evolution of the wave packet, specifically the Rossby wave packet, only in barotropic basic flows in order to clarify ideas, demonstrate the effectiveness of the theory, and show some new and fundamental results as well. The case in which the stratification and baroclinicity in the basic flows are both taken into account is postponed to Chapter 7.
