Abstract:
Based on NCEP／NCAR daily reanalysis data in July 2004, the moisture a nd wind fields of heavy rain events in Guangxi are analyzed. Results show that t he evaluation of heavy rain has a good correspondence to the variety of moisture and watervapor content increased before the heavy rain happened. The occurren ce and break of heavy rain is closely associated with the strengthening and brea k of summer monsoon. There is a remarkable difference of the vapor inflow and ou tflow between heavy rain period and nonheavy rain period. South China Sea is t he main water vapor source, while the Bengal and the West Pacific Ocean also pla y the important roles in heavy rain period besides South China Sea. And the wate r vapor income of heavy rain period is much more than that of nonheavy rain pe riod.
