闪电电流数据对雷电物理研究和雷电防护设计有重要参考价值,相比自然闪电电流难以直接精确测量,人工触发闪电技术是获得精确可靠雷电流信息的有效途径。为此,统计分析了2008—2014年广东野外雷电综合观测试验39次人工触发闪电中测量得到的106次回击（RS）、70次连续电流（CC）、374次M分量、32次初始连续电流（ICC）以及528次初始连续电流脉冲（ICCP）,并和国内外相关结果进行了对比。给出了人工触发闪电各个子放电过程的详细电流特征,包括几何平均值、上升沿时间、上升沿陡度、半峰值宽度、转移电荷等。比较结果表明：广东试验测得回击峰值电流的几何平均值强于加拿大CN塔上行负极性闪电;相比Florida人工触发闪电,广东试验测得ICC转移电荷量更大,平均电流强度更强,但持续时间接近,典型参数特征的统计结果在同一量级;高建筑物上行闪电的ICC脉冲具有更大的电流幅度、更短上升时间、更短的半峰宽度以及持续时间。试验结果显示：M分量幅值是ICC脉冲的3倍,上升时间和半峰宽约为ICC脉冲的1/2,且转移电荷量高于ICC脉冲;存在部分M分量,相比通常的M分量和ICCP,它们幅值较大、上升时间较短、半峰值宽度较窄、转移电荷量较大。

英文摘要：

Lightning current data play an important role in the research of lightnng physics and lightning protection, though it is difficult to measure directly. The artificially triggered lightning is a good method to get accurate current information. We analyzed 106 RS （return strokes）, 70 CC （continuous current）, 374 M-components, 32 initial continuous current （ICC） and 528 intial continuous current peaks（ICCP）, and then compared the parameters with the other reported results around the world. The detailed current properties of every subdischarge processes in triggered lightning, including average value, rise time, rise stepness, half peak width, and transfered charge are described. The results show that RS current peak in Guangdong is larger than the corresponding value of upward negative lightning generated from CN tower in Canada. The transferred charge and average current during ICC are larger than the corresponding triggered lightning in Florida, though their duration and other statistical charactersitics are similar.The ICC peaks during the lightnings generat- ed in high buildings show the characteristics of larger current, shorter rise time, small half peak width, and short duration. The amplitude of M components is three times of the ICC peaks, but the rise time and half peak width are 1/2 of those of the ICC peaks, and the transferred charge is larger than the corresponding values of ICC peaks. Some M components have larger amplitude, small rise time and small half peak width, and larger transferred charge compared with the regular M components and ICC peaks.
