Using data from the NCEP/NCAR renalysis the propagation path of ST anomalies inthe South Atlantic Ocean is inverstigated. This is done by lag-correlating SST anomaly fields with SST averaged over the Cape Basin. I tis found that SST anomalies origninate in the Brazil/Malvinas Confluence region, migrate witht he southern limb of the subtropical gyre towards South Africa and tehn enter the Benguela Current that transports them northwards.
