Abstract
Airflows over steep complex terrain with characteristic length scales of the order of kilometers contain the flow impingement, separation and reattachment. In order to develop an accurate model of simulating the above-mentioned topographic effects, we have been examining the large-eddy simulation(LES) technique using a finite-difference method(FDM). These LES codes are referred to as the RIAM-COMPACT(Research Institute for Applied Mechanics, Kyushu University, Computational Prediction of Airflow over Complex Terrain). In the present study, we tried to the calculation considering the meso-scale meteorological field obtained from CSU-RAMS(Colorado State University, Regional Atmospheric Modeling System).
