Extended Data Fig. 1: Observed CHIRPS (1981-2018) summer (June-September) precipitation characteristics over SREX regions considered in this study.
From: Enhanced risk of concurrent regional droughts with increased ENSO variability and warming
(a) Map shows the fraction of annual precipitation that falls in summer season. (b) Map shows the summer precipitation entropy value over land. (c) Significant (P-value < 0.05) linear regression coefficients between ENSO and JJAS precipitation. (d) Map showing the 10 SREX regions (maroon boxes) considered in this study. Maroon text indicates the fraction of each SREX region with high entropy values [entropy > 4.86, which is the median entropy value across 10 SREX regions] (teal) estimated from observed CHIRPS precipitation data (1981-2018) at 0.250 resolution. The regions shown in teal are used to estimate compound drought characteristics.
