利用2009年6-8月南京Doppler雷达资料和江苏闪电定位资料,通过对雷电活动过程与雷达回波强度、回波顶高及垂直累积液态水含量的特征关系的分析,得出适合于江苏地区夏季（6-8月）雷暴预警的因子：40dBz回波强度发展到7 km高度及以上,垂直液态水含量（VIL）值达到25 kg/m2,风场在雷电发生前多表现为强烈的辐合上升运动,回波顶高在雷电发生时均在9 km以上。实验结果表明,将上述4个因子结合分析,预警效果更好。

The analysis of characteristics for the lighting activity process,the intensity of radar echo,echo top and vertically integrated liquid is carried by using Doppler radar data and lightning location networks in Nanjing from June to August in 2009.The lightning warning factor which is suitable for Jiangsu summer（from June to August） is got.The results show the echo intensity of 40 dBz reaches 7 km above,VIL meets 25 kg/m2,wind field shows strong convergence ascent motion before the lighting,echo top is in the 9 km above when the thunderstorm occurs.It has been found that the combinative analysis of four parameters can play better warning effect.
