Fignre 4. Observed sea level along the equator from the TOPEX/Poseidon altimeter (left), simulated sea level along the equator (middle), and simulated sea level due just to wind-forced Kelvin waves along the equator (right). In each case a mean seasonal cycle based on 1993-96 has been removed. Temporal resolution is 10days for TOPEX/Poseidon, 5days for the simulation.

Figure 5. Simulated wind-forced Rossby wave sea level amplitude at 5｡? (left), western boundary-generated Kelvin wave amplitudes along the equator (middle), wind-forced Kelvin wave amplitude along the equator. The contour interval in the middle panel is 2cm, whereas it is 5cm for the two outer panels. Longitude axis for the Rossby wave panel has been flipped so that the interface between incident Rossby waves and reflected Kelvin waves at the western boundary is clear. In each case a mean seasonal cycle based on 1993-96 has been removed.
