Due to both bottom - boundary layer friction and interior adjustment, this coastal current anomaly facilitates the movement of warmer deep water upward onto the continental shelf and toward the coast (see Figure). (usclivar.org)
Would you accept that current SST (not current anomaly, but current local SST) is the result of a combination of cyclical variation plus GW? (realclimate.org)
A thorough discussion of a dark current anomaly observed during the warmup can also be found in this paper. (stsci.edu)
