Title: Chapter 12 Rossby Waves in a Rotating Stratified Fluid
Abstract: Publisher SummaryThis chapter discusses Rossby waves in a rotating stratified fluid. The chapter uses the fact that (for an inviscid fluid) potential vorticity is conserved, to study Rossby waves in a homogeneous rotating fluid. The chapter applies this principle to investigate Rossby waves in a rotating stratified fluid. One can assume that the perturbations from the equilibrium state are small and can consider the case where the gravitational potential G(r) = gz. This is the equation that describes the behavior of Rossby waves in a stratified fluid. A significant body of work has developed, which shows the importance of Rossby waves in understanding the movement of large scale disturbances in the oceans and the atmosphere. The chapter concludes that, for a given strength of stratification N and given depth h, Rossby waves are only influenced by stratification if the horizontal length scale exceeds the Rossby radius of deformation.
