要約(英語): Observation of lightning current by using Rogowski coils started in February 2012 at Tokyo Skytree, which is a 634-m high freestanding broadcasting tower. Electromagnetic field waveforms are also observed by capacitive antennas at several tens of kilometers from the tower. Simultaneously observed lightning current and electric field waveforms are reproduced by using an electromagnetic model of a return stroke on lossy ground with the help of NEC-4. Electromagnetic field waveforms are reproduced by using an inclined lightning channel reconstructed from observed images. It turns out that the electromagnetic field waveforms are considerably affected by lightning channel geometry and ground conductivity.
