From: Interaction between dry and hot extremes at a global scale using a cascade modeling framework

Spatial map of a–c maximum attributable fraction (AF) magnitudes that are statistically significant at 95% confidence level for the drought-heatwave cascade derived using (a) 1 percentile of daily root-zone-soil-moisture (RZSM), and 99th percentile of daily maximum temperature (Tmax) as threshold (D1pH99p), b 5th percentile of RZSM, and 95th percentile of Tmax as threshold (D5pH95p), and c 10th percentile of RZSM, and 90th percentile of Tmax as threshold (D10pH90p), calculated for the period, 1980–2018, and d–f corresponding lags for which the maximum AF magnitudes (shown in a–c) are observed (g, h) bivariate kernel density estimates (probability density shown by shading) calculated for the grid-point maxima of AF magnitudes and corresponding lag-times considering all grids identified as hotspots (AFT ≥ 15%).
