摘要
讨论了1991年5月上旬到7月下旬逐旬水汽通量的变化。来自孟加拉湾和来自南海的水汽通量各旬之间变化很大并且有正相关关系。这种变化引起进入江淮流域南界的水汽发生变化。导致江淮流域的水汽收支各旬不同。5月下旬和7月上旬,水汽收入达到峰值,为暴雨提供了丰沛的水汽。说明江淮流域的水汽主要来自孟加拉湾和南海。
Moisture transfer associated with the sustained heavy rain in 1991 over the Jianghuai valleyis analyzed,It is shown that 2/3 of the moisture that entered to the Jianghuai Valley during July1—10 1991 came from the Bay of Bangal and the remaining 1/3 from the South China Sea.The evolution of moisture transfer during May 1 to July 10 1991 shows that both the mois-ture transfer from the Bay of Bangal and from the South China Sea are enhanced simultanouslyand they are corresponding to the heavy rain over the Jianghuai Valley.
