There is a potential problem that hazardous and flammable materials are accidentally or intentionally released within urban areas. Our objective is to compare our LES results for distribution patterns of mean and fluctuating concentrations in various actual urban areas with the existing LES and experimental results for those in regularly arrayed obstacles, and investigate the influence of actual urban surface geometries on the characteristics of mean and fluctuating concentrations.
