Electric field and Maxwell current density measurements made below thunderstorms at Pune (India) have been analyzed to study the charging processes occurring during dissipation stage of thunderstorms. These observations suggest that during the dissipation stage of thunderstorm different charging processes contribute to the cloud electrification depending on the type of thunderstorms. Our observations suggest that updraft may not be sufficient to activate charging mechanism inside cloud during the dissipation stage in small thunderstorms. However, in big thunderstorms, non-inductive charging mechanism may be active during the dissipation stage. The recovery curves of electric field and Maxwell current density measured during dissipation stage of inverted polarity thunderstorms suggests that inductive charging mechanism may also contribute to the thunderstorm electrification.

雷暴消散阶段的充电过程

已经分析了在浦那（印度）雷暴下进行的电场和麦克斯韦电流密度测量，以研究雷暴消散阶段发生的充电过程。这些观察结果表明，在雷暴消散阶段，根据雷暴的类型，不同的充电过程对云带电有贡献。我们的观察表明，在小型雷暴的消散阶段，上升气流可能不足以激活云内部的充电机制。然而，在大雷暴中，非感应充电机制在耗散阶段可能是活跃的。
