摘 要: 分析了1994年前汛期广东区域大气水汽与水汽输送,指出了这段时期水汽含量和水汽输送特征,水汽通量散度时空分布及变化,水汽突变(主要由高空湿层增厚引起)与夏季风建立和“946”暴雨的发生的关系.观测研究表明,在暴雨期,在时间尺度上水汽散合是短周期的,在垂直方向上有多个水汽无辐散层. The atmospheric moisture and the trasfer of water vapor over Guangdong area in the first half rain season in 1994 are analyzed. The feature, the distribution and variation of water vapor divergence and relation between water vapor and onset of summer monsoon and occurrence of heavy rain are studied. The results show that the fluctuation of water vapor is in short period and there are more than one non divergence layers during heavy rain.
