Figure 10 December-April anomalies averaged across the central North Atlantic box (60o-30oW, 35o-45oN) during the month of maximum mixed layer depth. The scale for MLD is shown on left (m), while scales for SST (oC) and winds (ms-1) are shown on right. At decadal periods MLD and SST both show increasing trends.
