Abstract : Oscillating bipolar field changes due to nearby lightning return strokes (up to 25 km distance) were sometimes recorded during winter thunderstorms in Japan together with ordinary unipolar field changes as recorded in summer thunderstorms. In order to understand the reason for the appearance of an oscillating field change, we calculated the return stroke current along a lightning channel with a transmission line model. The calculation shows that the return stroke current oscillates because of the relatively small volume of the winter thundercloud. (Author)
