It is highly important in Japan to choose a good site for wind turbines, because the spatial distribution of wind speed is quite complicated over steep complex terrain. We are developing the unsteady numerical model called the RIAM-COMPACT^<[○!R]> (Research Institute for Applied Mechanics, Kyushu University, Computational Prediction of Airflow over Complex Terrain). The RIAM-COMPACT^<[○!R]> is based on the LES (Large-Eddy Simulation) which is a kind of a turbulence model. The object domain of the RIAM-COMPACT^<[○!R]> is from several m to several km, and can predict the airflow and gas diffusion over complex terrain with high precision. In the present paper, an influence of elevation data on topography-induced turbulence of wind turbine neighborhood was examined.
