Fig. 5: Comparison of MCA analysis of sc-PDSI and SST anomalies between two periods (1901–1960 and 1961–2020).
From: Regional responses to oceanic variability constrain global drought synchrony

A Leading mode during 1901–1960, showing heterogeneous correlation coefficients between SST PC1 and sc-PDSI over land, and sc-PDSI PC1 and SST anomalies over oceans. B Same as (A), but for 1961–2020. C Difference in leading modes between the two periods (1961–2020 minus 1901–1960).
