Figure 2

Timeseries of the cold tongue variability as defined as the SST averaged over the Wyrtki box (black). Dash black line represents the SST variations of the waters that are denser than 22.5 kg/m3, and the light blue and blue lines are respectively the SST variations for a density criterion of 23.0 and 23.25 kg/m3, respectively. The red curve is derived from the NCEP reanalysis for the 23.0 criterion. The spreading around the light blue curve is obtained by considering a +/− 0.15 for the SSS field in the determination of the surface density of waters. Unit is in °C.
