In order to simulate unsteady three-dimensional airflow around urban city area with characteristic length scales of the order of kilometers, we have been examining the large-eddy simulation (LES) technique using a finite-difference method (FDM). In this paper, using the LES technique, we have performed the calculation of buoyant gas diffusion around real urban area with huge computational grids. The various patterns of gas diffusion are clarified, and airflow is also locally accelerated or decelerated, due to the topographic and the obstacle effects.
