| 摘 要： | 应用常规、加密气象资料及卫星云图,分析了2004年7月16～17日沙澧河流域特大暴雨成因.结果表明：高、低空急流耦合区中西南低涡及MCC特征云团的形成和维持是造成此次特大暴雨的直接影响系统.提出利用逐时的中尺度辐合中心、卫星红外云图云顶亮温及雷达回波降水率做中尺度雨团量级预测思路.

| Abstract: | Using satellite cloud pictures and data from the intensive and conventional observation, the reason of the heavy rainfall event on 16-17 July 2004 over Shali river area is studied. The results show that the event is directly affected by the formation and evolution of southwest vortex and MCC cloud cluster which locate in the intersection region of the upper-level jet and the low-level jet. In addition, a thought of how to use the mesoscale convergence center, TBB of convective cloud and the radar echo for rainfall rate to predict the mesoscale rain cluster is presented. |
