چکیده انگلیسی
Our large dataset of δDwax from trees and grasses that aimed to mirror the variability of environmental factors over geological time frames showed the lapse rates were significant, but much smaller than in previous studies. Most importantly our result demonstrated that the lapse rate significantly differed for both transects (p = 0.0068), i.e. 0.87 ± 0.71â°/100 m (R2 = 0.28, p = 0.2841, n = 6) and 2.28 ± 0.82â°/100 m (R2 = 0.34, p = 0.0135, n = 17) for Indian monsoon and Westerly dominated areas, respectively. This suggests that different moisture sources might strongly affected the observed lapse rates. In consequences altitude reconstructions are strongly complicated in areas with likely changing air masses like the Tibetan Plateau.
