Temporal variability of the Southern Annular Mode (SAM) and El Niño Southern Oscillation (ENSO). (a) Mean Oceanic Niño Index (ONI). (b) SAM. (c) SIC during the summer (from January to March) in the period 1990 to 2014. (d) The relationship between the ONI and SAM in the period 1990 to 2014. (e) The relationship between the SIC and ONI (or SAM) during in-phase periods (+SAM/La Niña and −SAM/El Niño). The shaded areas in (a–c) indicate the mooring campaign periods.
