On the Nature of Large Scale Wave Disturbances in the Equatorial Lower Stratosphere

Abstract

Large scale wave disturbances in equatorial region, and, in particular, those described by Maruyama(1967), are discussed in terms of forced oscillation. In doing this we are able to explain the importance of the waves' tilts, the role of the beta effect, and the waves' contributions to the mean zonal momentum. Consideration of the last items leads us to conjecture on the nature of those disturbances in the equatorial stratosphere which were not isolated in the analysis of Maruyama.
