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. So 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. In this paper, we have studied about large-scale analysis of lightning electromagnetic field with real urban models considering buildings using our MW-FDTD with parallel computation. We have given an account of effects on electromagnetic field by buildings.
