Abstract EN
Based on the precipitation δ18O values from the datasets of the Global Network of Isotopes in Precipitation (GNIP), the National Centers for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR) Reanalysis data, and previous researches, we explored the temporal and spatial variations of precipitation δ18O in a typical monsoon climate zone, the Pearl River basin (PRB), and adjacent regions.
The results showed that the temporal variations of precipitation δ18O for stations should be correlated with water vapor sources, the distance of water vapor transport, the changes in location, and intensity of the intertropical convergence zone (ITCZ) rather than “amount effect.” Meanwhile, local meteorological and geographical factors showed close correlations with mean weighted precipitation δ18O values, suggesting that “altitude effect” and local meteorological conditions were significant for the spatial variations of precipitation δ18O.
Moreover, we established linear regression models for estimating the mean weighted precipitation δ18O values, which could better estimate variations in precipitation δ18O than the Bowen and Wilkinson model in the PRB and adjacent regions.
