a, b Correlations for the observed SPEI and SST for the monsoon season obtained from the first leading mode of MCA for 1951–2018, and c, d composite of heterogeneous correlations between monsoon season SPEI and SST from the first leading mode of MCA from all 40 ensemble members of CESM-LENS. Numbers in brackets denote the squared covariance fraction (SCF) explained by the first leading mode. For CESM-LENS, we calculated the mean SCF from all ensemble members.
