Abstract(in Japanese) (See Japanese page)
Abstract(in English) Analysis of lightning electromagnetic field using the finite-difference time-domain (FDTD) method have been studied in recent year. However, large-scale analysis on real environment have not been considered, because the FDTD method requires huge computational cost on large-scale analysis. We proposed a three-dimensional moving window FDTD (MW-FDTD) with parallel computation and applied this method to large-scale analysis of lightning electromagnetic field with a real terrain model. However, we have used a simple linear current source for lightning channel. In this paper, we have studied about analysis of dependency on channel angle of lightning electromagnetic field using our MW-FDTD with parallel computation with a digital terrain model. We have given an account of effects on electromagnetic field by channel angle.
