用时面深概化法估算清江中上游流域可能最大暴雨

Estimation of the Probable Maximum Storm in Upper and Middle Reaches of Qingjiang Rive Basin Using Enveloping Time-area-depth Curves Approach

在分析清江流域暴雨洪水特点及含清江流域暴雨一致区内暴雨特性的基础上，推测出形成清江中上游可能最大暴雨的天气形势和梅雨形势类似，暴雨为梅雨雨带中的暴雨，水汽入流方向为西南方向，采用时面深概化法估算了清江中上游流域２４ｈ和３ｄ可能最大暴雨。

Charactors of the storms and floods happened in Qingjiang River Basin and meteorological homogeneous region where Qingjiang River flows have been analysed in this paper. Based on above charactors,it is conjected that the synoptic situation of the storms in Qingjiang Valley is similar to plum rains synoptic situation in the valley. In the period,the flood-producing storms in Qingjiang Valley often appear.The moisture forming heavey rainfall in Qingjiang Valley comes from the south-west.In this paper,the probable maximum storms for 24h and 3d in Qingjiang Valley are estimated using enveloping time-areadepth curves approach.
