| 摘 要： | 2010年6月19日夜间,贵州北部普降暴雨及大暴雨,分析认为,这是由位于贵州中北部、重庆南部的一个中尺度对流复合体(MCC)造成的.利用常规的micaps观测资料、自动站资料及卫星tBB和雷达资料分析了这次MCC的云图和回波特征,结果表明,这次MCC系统造成的降水范围大、雨强强、分布较集中,卫星云图上tBB最小值达-90℃以下,-80℃冷云区面积和MCC的总降水量存在一定的正相关,-80℃冷云区面积越大,MCC总降水量也越大.MCC在雷达回波上表现出一条类似飑线的带状回波和零星的块状回波,带状回波造成的降水强度大,常常造成暴雨和大暴雨.

| Abstract: | On night of June 19th,2010,severe torrential rains hit north of Guizhou.Analysis shows that it was caused by a MCC developed in areas between mid-north of Guizhou and south of Chongqing.In this paper,routine observation data from MICAPS,data from automatic observations,satellite tBB data and radar data are used in analyzing cloud image and radar echo features of MCC.Results show that due to MCC,this rain event featured large-area,high intensity and concentrated distribution.The minimum value of tBB was over... |
