要約(英語): Numerical simulations of surface streamer propagation in atmospheric air are carried out, and calculation results well correspond with experimental results by Pockels sensor system. Propagation and decay processes of the surface streamer are clearly specified from the calculation result. Number densities of charged particle are 1020m-3 and 1018m-3 in positive and negative surface streamers, respectively. In the positive polarity, the cathode fall region forms between the surface streamer and the dielectric barrier, and reduced electric field reaches about 1000 Td at the streamer head and 10-20 Td at the streamer channel. In the negative polarity, the streamer contacts the dielectric barrier surface, and reduced electric field reaches about 150 Td at the streamer head and 50 Td at the streamer channel.
