Based on the data recorded at Shijazhuang,Xi′an, Guangzhou, Kunming and HongKong,an apparent positive correlation between the precipitation δ~(18)O and temperature inthe mid latitude, and negative correlation between δ~(18)O and precipitation amount for thelowlatitude are found respectively.The result supports that Reyligh modeling is an appropri-ate tool to explain the statistical relations between the annual mean δ~(18)O and correspondingtemperature. If the eddy transport of atmospheric moisture is assume...
