Short summary
The paper analyzes sea surface height anomalies (SSHAs) observed in the Indian Ocean south of Australia by combining several known methods for phase speed determination. The observed speeds and the meridional variations of the amplitudes of these signals are compared with two theoretical expressions for the phase speed and meridional amplitude structure of Rossby waves. The paper concludes that both the meridional structure of the SSHAs and their phase speeds fit those of trapped Rossby waves.
