袖珍云闪（ CIDs：compact intracloud discharges）是一种特殊的云闪现象，与常规云闪放电相比有很多特殊性：辐射双极性脉冲并通常单独出现、电场持续时间短、高频辐射强等。通过对袖珍云闪放电模型的建立，根据麦克斯韦方程组推导了CIDs辐射电磁场的计算公式，仿真计算了袖珍云闪的电磁场波形；并与实测波形进行了对比分析。分析结果显示，经该模型计算的袖珍云闪的电磁场波形与实测结果有较好的一致性；并讨论了在放电过程中，放电位置、放电通道长度以及通道的倾斜角度对其电磁场波形特征的影响。

Compact intracloud discharges is a special kind of lightning, which has a lot of particularity:the ra-diation field pulses produced by CIDs are single and referred to as narrow bipolar pulses; the waveforms have a short duration;the high frequency radiation is strong, etc.Model of CIDs was build and derived the calculation for-mula of CIDs radiated electromagnetic fields according to Maxwell's equations, simulate the electric field of CIDs and compared with the detected result.It shows that the simulation result has a good consistency with the real de-tected result.The discharge position, the discharge channel length and the angle’ s influence are also discussed to the feature of the electric field of CIDs.
