中文摘要: 分析1996～1997年4次冷涡雹暴过程中获取的闪电定位和713雷达回波资料。其结果表明：在降雹前15分钟，闪电次数存在一个酝酿和跃增过程，到降雹出现时，闪电次数达到最大值；降雹过后，闪电次数缓慢下降。其中云内闪电和总闪电频数分布与这一现象对应较好。通过对闪电闪击区域与地面降雹位置进行叠加和比较，发现两者吻合较好。应用闪电位置和强度资料与雷达回波图象相叠加，发现闪电出现频繁的区域，正好对应于雷达强回波区。

Abstract:The data of single station lightning detection and ranging system and 713 radar echoes achieved from 4 cold vortex hailstorm events from 1996 to 1997 are analyzed. The results show that the number of times of lightning have a brewing and leaping procedure before the hail begins to drop 5 minutes,it reaches the maximum when the hail begins to drop and after the hail dropping it descends slowly. The distribution of cloud discharge and total lightning frequency corresponds with this phenomenon better. Comparing the ground area hitted by lightnings and the ground place of hails dropping on,it is found that the area coincides with the place well. Put the lightnings' place and the intensity data on top of the radar echoes picture,it is found that the place where lightnings appear frequently is just the place where the radar echoes are strong.
