Two models of wave propagation which predict oscillations with the observed properties. The models incorporate the monotonic variation of atmospheric rotation from nearly zero at the planetary surface to the 4 day rotation at the cloud tops. Wind shear precludes separability of the wave propagation equation, in contrast to the simpler terrestrial problem. The problem is solved by expanding in spherical harmonics (the spherical model) or by simplifying the latitude dependence (the beta plane model). Preferred modes of oscillation are found by imposing forcing over a wide range of frequencies and looking for those frequencies at which the atmospheric response is greatly enhanced. Results reveal two types of planetary scale waves which explain the observations upward propagating gravity waves, which travel slightly faster than the 4 day rotation, and upward propagating Rossby waves, which travel slightly slower.
