NOTES AND CORRESPONDENCE On the Reemergence of North Atlantic SST Anomalies
The reemergence mechanism, whereby temperature anomalies extending over the deep winter mixed layer are stored beneath the surface in summer and are reentrained into the mixed layer when it deepens again in the following autumn and winter, is studied in the North Atlantic using approximately 40 year...
