Figure 10.6 Time-longitude plot of sea-level anomalies in the Equatorial Pacific observed by Topex/Poseidon. Warm anomalies are light gray, cold anomalies are dark gray. The anomalies are computed from 10-day deviations from a mean surface computed from 10/3/1992 to 10/8/1995. The data are smoothed with a Gaussian weighted filter with a longitudinal span of 5° and a latitudinal span of 2°. The annotations on the left are cycles of satellite data.
