Indian monsoon influences altitude effect of δ18O in precipitation/river water on the Tibetan Plateau

Isotopic evidence for the moisture origin and composition of surface runoff in the headwaters of the Heihe River basin

“…The marked differences among the monsoon zone, transition zone, and westerly zone in the Tibetan Plateau reported by Yao et al [37] indicate that differences in these water sources strongly affected 18 O for the headwaters of the Heihe River basin and for the westerly zone [37], and the dissimilarity with the variations for Lhasa and Hong Kong, reveal that the moisture entering the headwaters of the Heihe River basin was derived predominantly from the westerly and polar air masses. Precipitation δ…”

Stable isotopes of surface water across the Longmenshan margin of the eastern Tibetan Plateau

“…Using this composite data set, we derived the second-order least squares regression for each isotope with elevation: [Liu et al, 2008b[Liu et al, , 2009 (Figure 5), the isotope elevation gradient is distinct from those along other boundaries of the Tibetan Plateau. On the south slope of the Himalaya and southern Tibet, the d 18 O w altitudinal gradients are higher (20.320.23&/100m) [Garzione et al, 2000;Zhang et al, 2002;Ding et al, 2009;Hren, 2009;Yao et al, 2009;Wen et al, 2012]. In contrast, on the northern and southeastern part of the Tibetan Plateau, the gradients are as low as 20.15 &/100 m Ding et al, 2009;Bershaw et al, 2012], and 0.19&/100 m [Hoke et al, 2014], respectively.…”

Stable isotopes in monsoon precipitation and water vapour in Nagqu, Tibet, and their implications for monsoon moisture

“…With Lhasa station becoming member of this project in 1986, a dozen monitoring stations across the Qinghai-Tibetan Plateau (QTP) of China has gradually been set up to provide a continuous isotopic record of precipitation over the last 10 years (Yao et al, 2009). Because the isotopic composition of the precipitation on the plateau can vary at fine spatial and temporal resolution, field studies are also needed to capture dynamics of seasonal and even diurnal scales, especially the "transitional region" of the northern limits of the monsoon.…”
