Figure 5: Seasonal average variances for the SLA (sea level anomalies, full line), SST (sea surface temperature, dotted line) and ocean color (dashed line) data as a function of latitude resulting from a meridional average (between 15-45žE) of the two-dimensional power Hovmöller. a) Spring, b) Summer, c) Fall and d) Winter. Variances are normalized by the maximum variance achieved for each signal over one year, October 1997-September 1998, and between 36žS and 45žS.
