The relationship between the boreal winter El Niño SST anomaly and boreal spring tropical Atlantic SST gradient (North Atlantic minus South Atlantic) is investigated using a long, detrended SST record.

The ratio of the numbers of concordant and discordant cases is 4:3 overall, indicating strong non-ENSO influences on the Atlantic SST gradient.
