Abstract

By dint of isotope data of the atmospheric precipitation and NCEP reanalysis data, the changes characteristics of precipitation in Baotou were analyzed. It showed a positive correlation between the weighted average of 18O and precipitation, which was related to the semi-arid climate of Baotou. The slope and intercept of local meteorological water line (LMWL) of Baotou were lower than that of Global Meteorological Water Line (GMWL). Combined environmental stable isotope data of precipitation with Backwards Trajectory model, it showed: 1) Baotou was dominated by westerly continental vapor throughout the year, and also was influenced by the oceanic vapor in spring and summer. 2) Owing to the high temperature, Baotou was remarkably effected by local evaporation of water vapor in spring and summer.
