a) SST root-mean-square variance (contour interval of 0.5°C with light shading < 0.25°C and dark shading > 0.5°C). b) Time series of Nino3 area mean SST anomaly (°C). The thin solid line is the monthly anomaly and the thick dashed line is the 120-month running mean. The annual cycle is removed before analysis and the result for the last 48 years of the model run is depicted for figure clarity.
