本文分析了2012年广州地区6次雷暴过程的负地闪中不规则脉冲簇(chaotic pulse trains,CPT)放电事件的发生规律. 结果表明:CPT是负地闪整个放电过程中普遍存在的放电现象,在323次负地闪中有243次出现了CPT放电事件,比例达到了75.2%,并且能够发生在负地闪的首次回击之前、回击之间以及最后一次回击之后,其中有66.7%的继后回击之前和11.5%的最后一次回击之后发生了CPT. 研究也发现,CPT在继后回击之前有四种分布类型:单独出现一次CPT-c(与继后回击相连的CPT)、单独出现一次CPT-i(与继后回击有一定时间间隔的CPT)、 同时出现CPT-c和CPT-i以及同时出现多次CPT-i,其中,单独出现一次CPT-c类型最为多见,39.4%的继后回击之前为此类型,而在第一次和第二次继后回击之前更容易出现多次CPT的现象,分别占到对应次序回击总数的9.4%和7.7%. 而随着继后回击次序的增加,其之前发生CPT的概率呈减小的趋势,并且除了第一次和第二次继后回击以外,其他继后回击之前CPT-c的出现频次大于CPT-i. 另外,CPT-i和最后一次回击之后的CPT均叠加在K变化上,部分回击间的CPT也能够发生在J过程中.Occurrence regularity of chaotic pulse trains (CPT) discharge event in negative cloud-to-ground (CG) lightning during six thunderstorms are analyzed in this paper. Results show that CPT is a common phenomenon throughout the negative CG lightning discharge process, 243 times of CPT discharge events occurs during 323 negative CG lightning, a proportion reaching 75.2%. CPT in negative CG can occur before the first return stroke, between the strokes, and after the last stroke. The proportion of 66.7% of the total subsequent strokes is preceded by CPT, and CPT occurs after 11.5% of the total last strokes. It is also found that there are four distributions prior to subsequent strokes: single CPT-c (CPT connecting with subsequent strokes), single CPT-i (CPT occurring in an interval between CPT and return strokes), CPT-c and CPT-i occur concurrently, and several CPT-is appear concurrently. Single CPT-c is the most common, 39.4% of subsequent strokes are preceded by single CPT-c, and several CPTs are easier to occur before the first and second subsequent strokes, which are respectively the corresponding strokes 9.4% and 7.7% of the total number. With the increase of the order of subsequent stroke, there is a decreasing trend for the occurrence of CPT, and in addition to the previous two subsequent strokes, the number of CPT-c is obviously greater than CPT-i before the others. In addition, CPT-i and CPT-a both occur to add on the negative CG K-change, and some also correspond to the process of J-change in the slow electric field wave.
