Figure 2: Observations from the two satellite data sets over ten days centered on August 16, 1997. Panel (a) shows a ten day composite of velocities inferred from tracking thermal patterns. Velocities are missing in regions with persistent clouds and weak thermal gradients. Panel (b) shows surface height anomalies from TOPEX/POSEIDON (large diamonds) and ERS-2 (steeper tracks) altimeters over the same time period.
