Abstract

Monsoon plays an important part in the summer precipitation over southern China.Different monsoons carrys different inflow vapors into China and control the temporal and spacial distribution of precipitation.During the period of July,2005,based on the CHNIP stations,which are located in southern China,we collected monthly composite samples.The analysis of the meteorological data and the δ values of the precipitation samples indicate that the distribution characteristics of the stable isotopes of precipitation could properly portray the origin of the summer monsoonal precipitation and its vapor inflow corridors.Furthermore,we discuss the amount effect,altitude effect,temperature effect and the correlation between δ18O and the relative humidity.

Key words： summer monsoon; precipitation; vapor inflow corridor; δ18O; southern China
