The purpose of this study is the analysis of the turbulent wind on the complex terrain and the modeling of the fluctuating wind for the inlet condition of the numerical wind prediction. The inlet condition with the turbulent wind is significantly important for the fluctuating wind simulation, and the several methods, for example, randomness, roughness block, re-scale cyclic boundary, were designed to generate the turbulent for the inlet condition. However, a method, which is suitable for the simulation of the fluctuating wind on the complex terrain, does not appear. The approach, which is the LES calculation of the wind on a real site, would offer the much information of the wind on the complex terrain. From the temporal wind data of LES calculation, the wind profiles and the turbulences were achieved and the modeling of the inlet flow condition might be possible.
