中文摘要: 运用NCEP／NCAR每日4次全球再分析1°×1°网格资料，分析了2004年7月广西汛期暴雨过程
中的水汽和风场变化情况。结果表明，在暴雨过程中暴雨发生发展与广西区域水汽的变化有
很好的对应关系，水汽含量的增强一般出现在暴雨发生之前。广西区域暴雨发生和间歇与夏
季风的加强及中断关系密切。广西区域暴雨期与非暴雨期水汽收支情况及其输送路径的差异
明显。暴雨期，广西区域的水汽源主要为孟加拉湾、南海、西太平洋；非暴雨期，水汽的主
要来源是南海。暴雨期的水汽收入远远大于非暴雨期。
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 water vapor 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 non heavy 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 non heavy rain pe
riod.
