Short summary
Local and upstream specific humidity is the main factor determining non-monsoon season d-excess variability over southeast Tibetan Plateau (TP) due to the intrusion of cold and dry air from upper levels. During the summer monsoon season, d-excess and δ18O mainly reflect the effect of raindrop evaporation which leads to lower vapor δ18O but higher d-excess values. These findings provide new insights into using water isotopes to track moisture sources and dynamics over the TP.
