Figure 4: Frequency-wavenumber spectra computed from 7 years of T/P data along 24°N and 24°S over the longitude ranges labeled on each panel. The dispersion relation computed from the classical theory and the extended theory of Killworth et al. [1997] are shown by the white and black circles, respectively. These circles and the associated confidence intervals at each wavenumber correspond to the median and central 75% of the distribution of individual estimates along the longitudinal section over which the spectra were computed.
