Sea surface height anomalies demonstrating eddy effects
Figure 3-16 A time-longitude plot of sea surface height anomalies (right) at 21.3°N shows that when high monthly average sea levels are recorded at Honolulu (left, red line), they often originate further east (right, eddies as red contours moving westward over the x-axis as time progresses on the left y-axis).
