摘要
通过对６次不同云系电特性、回波、对流及降水特性的综合分析，探讨了它们之间的相关性。结果表明：除不稳定能量外，－１０℃层和０℃层高度以及他们之间的高度差、０℃层与云顶的高度差也是表征雷暴动力和电特性的重要参量；雷暴云起电过程对冰相作用有较强的依赖性；雷暴中的电活动与对流活动成正相关，闪电多发生在３０ｄＢｚ强回波高度大于－１０℃层高度时段内，强烈的电活动与强降雨有很好的对应关系，而与一般性降雨对应关系较差；在雷暴消散期。
In this paper,electric and echo characteristics,convection and precipitation were analysed and correlation between them were investigated in 6 different cloud systems The results indicated that except instability energy,-10℃ and 0℃ temperature levels,altitude difference between them,altitude difference between 0℃ temperature level and the top of cloud were important parameters that represented dynamics and electric characteristics in thunderstorm The electrification processes in thunderstorm strongly depended on ice phase of cloud The relationship between electric activity and convective activity was positive correlation Most of lightning are occured during height for 30dBz echo was higher than -10℃ temperature level The intense electric activity corresponded to heavy precipitation and didn't correspond to weak precipitation The lightning may be influence on characteristics of thunderstorm during dissipating stage
