Figure 4. Interannual TP/ERS SLA (top). Interannual 300 m pycnocline depth
anomaly from the model forced by wind stress curl and boundary condition
(middle). Interannual 300 m pycnocline depth anomaly from the model forced
by wind stress alone (bottom) at latitudes of 22 °S, 26 °S and 30 °S. We
used for the model a decay time of 300 days and the observed phase speed
(of the order of 1.5 times the theoretical one). First and second baroclinic
modes were used with wind projections of 1.35 and 0.64 and internal wave
phase speeds of 2.6 and 1.22 m s-1, respectively.
