Seasonal cycle of the standard deviation of interannual equatorial Pacific SST and outgoing longwave radiation anomalies. The seasonal cycle of standard deviation for a SST (unit: K) and b outgoing longwave radiation (OLR, unit W m−2) is presented from March, instead of from January—this represents the ENSO signature around the peak of its variations better. Monthly SST anomalies55 and OLR anomalies56 for the period 1982 to 2015 were used in the calculation. Before we calculated their standard deviations, we averaged SST anomalies and OLR anomalies over 5°S to 5°N. The data for all months of 1982 and 1997 were excluded from the analysis
