Fig. 10. The monthly circulation patterns in 1999, reconstructed from the model long-term mean circulation field and the monthly satellite-derived current anomalies. (A) 50-m in April, (B) 50-m in June, (C) 1-m in June and (D) 50-m in June. The anomaly currents are assumed to be depth-invariant in (A), (B), and (C), and to be variable linearly with depth with the bottom value of zero in (D). The 200-, 1000-, and 3000-m isobaths are also depicted.
