The synthetic power spectra contain the classical equatorial Rossby modes, as well as a rich spectrum of additional modes.

Webtimescale for rotation to be important and for the Rossby number to be small. The dynamics of Rossby waves has been examined. These are wave motions that require a background gradient of potential vorticity for their propagation. The mechanism of pro-duction of large scale Rossby waves by flow over topography has been discussed together WebRossby waves follow propagation pathways (‘rays’) in an approximate sense, and these rays are bent by variations in large-scale PV from the time-averaged winds, ... the theoretically …

In Hoskins and Karoly (1981, hereafter HK), the theory of waves propagating in a slowly varying medium was applied to Rossby waves propagating in a barotropic atmosphere.

The Rossby mode provides a negative feedback that regulates the planetary spin and mass. We compare the growth rate of the two modes as a function of the width of BL, the Mach number, and the spin rate of planets.
