摘要
对2002年6月7日至9日发生在盆地东北部遂宁市和南充市的特大暴雨雷达回波演变特点、高度、强度及外形特征进行了分析。得出:雷达回波不断从盆地南部以逆时针方向朝盆地东北部汇合,形成50dbz左右,高约14km的强中心区域,该回波在盆地东北部累计活动时间长达10h以上,直接导致了这次特大暴雨发生。这对今后类似天气过程雷达回波信息的有效利用提供了参考依据。
The features of the evolvement, height, intensity and figure of the radar echoes relevant to the torrential rainstorm in Suining and Nanchong area between 7 and 9 of June, 2002 is analyzed. The radar echoes converge anticlockwise from south to east of the Sichuan basin and form a intense echo center with about 50dbz and 14km height lasting for ten hours in northeast basin. Thus the torrential rainstorm is caused directly. This is of significance for the effective prediction of the similar weather procedures by using radar data.
