The southeastern periphery of the Tibetan Plateau (SEPTP) was hit by an extraordinarily severe drought in autumn 2009. Overall, SEPTP has been gripped a sustained for six consecutive years. To better understand physical causes these types and frequent droughts thus to improve their prediction enhance ability adapt, many research efforts have devoted disastrous SEPTP. Nonetheless, whether likelihood strength SEPTP, such as that 2009, affected anthropogenic climate change remains unknown. This study first identifies atmospheric circulation regime responsible then explores how human-induced It is found conditions driven Indian–Pacific warm pool (IPWP) sea surface temperature (SST) through strengthening local Hadley anomalously cyclonic motion over South China Sea. Ensemble simulations models demonstrate robust increase dry meteorological seen during 2009 due global warming. Given warming expected continue into future, results suggest it likely will become more common
