Figure 9

Spatial distribution of mean weighted precipitation  δ18O values over Pearl River basin of China based on the Kriging method from 1980 to 2011. Note: (a) represents meteorological stations in the Pearl River basin; (b) represents spatial distribution of the mean weighted annual precipitation  δ18O values by (8); (c) represents spatial distribution of mean weighted precipitation  δ18O values for the summer monsoon period by (9); (d) represents spatial distribution of mean weighted precipitation  δ18O values for the nonsummer monsoon period by (10).
