摘要
提出了一种异常简单的球状闪电模型，将其描述为一个被较冷空气包围的炽热、导电空气的高带电球体。该导电球体具有净多余电荷。此电荷将产生电晕放电，加热周围空气，从而维持球本身的温度。给出的数值模拟结果似乎与许多目击者的报告相符。文中论证此类球体很可能带正电。

备注
28 pages. 7 figures. The numerical simulations have been redone using a variant of the method introduced in the author's arXiv:2004.10653 (Foo Fighters and Microwave Oven Plasma Balls). This more accurately captures the expansion/contraction of the ball. The results and conclusions are largely unchanged, however
