“…The impact may be caused by individual non‐extreme events (Seneviratne et al ., 2012), and thus, the compound event with individual variables at a moderate level could also seriously affect ecosystems and society, which deserves appropriate attention. Following previous studies using percentile‐based thresholds to characterize compound events (Beniston, 2009; López‐Moreno et al ., 2011; Fortin and Hétu, 2013; Hao et al ., 2013; Kirono et al ., 2017; Martin and Germain, 2017; Zhu and Troy, 2018; Li et al ., 2019), we defined compound dry and hot events as the concurrence of seasonal precipitation lower than the 30th percentile threshold and seasonal temperature higher than the 70th percentile threshold (denoted as P < 30th and T > 70th). Based on previous studies (Hansen et al ., 2012; Coumou and Robinson, 2013), we chose 1951–1980 as the reference period because it was identified as a period with relatively stable global mean temperature.…”
