摘　　要：强对流天气是夏季长江中下游地区多发的灾害性天气,其天气过程的产生和发展受诸多内外因素的影响,如水汽条件、大气垂直运动等。2008年5月27日12:19在江苏省南京地区发生的强雷暴天气是1次典型的强对流过程。笔者通过运用多途径分析方式去分析此次过程,使用较为全面的探测资料力求更加准确地分析判断雷暴生命期特征。分析结果表明:雷暴之前南京地区持续高温使该地蓄积了大量不稳定能量是此次雷暴的先决条件,充足的水汽供应、强烈的大气垂直运动及大气中的不稳定层结为此次雷暴天气提供了必要的条件,南下的冷空气触动了不稳定能量是此次雷暴的诱发因素。Strong convective weather is the severe weather frequently occurred within the regions of Yangtze middle and lower reaches during summer. The emergence and development of this weather are affected by multiple internal and external factors, such as water vapor condition, atmospheric vertical movement and so on. It is a typical strong convective process occurred in Nanjing region of Jiangsu Province at 12：19 on May 27, 2008. The multiple ways were used to analyze this process with more comprehensive detective data for more accurate analysis and this thunderstorm＇s characteristics of periodical life were estimated. Before the occurrence of the thunderstorm, the high temperature persisting in Nanjing region was found, which had cumulated mass instable energy, should be seen as the prerequisite, and the adequate supply of water vapor, the strong atmospheric vertical movement and the atmospheric instable lamination were the necessary conditions for this thunderstorm. Besides, the southward cold air stirred up this instable energy, which was the induced factor of this thunderstorm.
