Figure 3: Phase speeds estimated from 7 years of T/P data (a) and 3 years of Run 11 of the POP model (b) based on the classical theory (solid line) and from the T/P and POP SSH fields in the Pacific (solid circles) and the Atlantic and Indian oceans (open circles). The ratios of the observed phase speed to the phase speed predicted based on the classical theory and the extended theory of Killworth et al. [1997] are shown in the middle and bottom panels, respectively.
