Rapid warming has been observed in the high-altitude areas around the globe, but the implications on moisture change are not fully understood. Here we use tree-rings to reveal common moisture change on the southeastern Tibetan Plateau (TP) during the past five centuries, and show that regional moisture change in late spring to early summer (April-June) is closely related to large-scale temperature anomaly over the TP, with increased moisture coincident with periods of high temperature. The most recent pluvial during the 1990s-2000s is likely the wettest for the past five centuries, which coincides with the warmest period on the TP during the past millennium. Dynamic analysis reveals that vertical air convection is enhanced in response to anomalous TP surface warming, leading to an increase in lower-tropospheric humidity and effective precipitation over the southeastern TP. The coherent warm-wet relationship identified in both tree-rings and dynamic analysis implies a generally wetter condition on the southeastern TP under future warming. STUDY NOTES: Southeastern Tibetan Plateau April-June self-calibrating Palmer Drought Severity Index (scPDSI) reconstruction for the past 500 years, based on two Abies forestii tree-ring chronologies from the southern Shaluli Mountains. The tree-ring data are archived in the International Tree-Ring Data Bank (ITRDB), site codes CHIN019 and CHIN075.
