In this paper, the Computational Fluid Dynamics (CFD) simulation of wake turbulence was performed by employing weather prediction data as the initial and boundary conditions. The weather prediction data was provided by the Down-Scaling Simulation System which was developed as mesoscale model by Atmospheric Science Laboratory, Tohoku University, and it showed qualitative agreement with actual weather observed at Sendai airport. In this wake turbulence simulation for the case of the horizontal roll convection currents in sea breeze, the initial and boundary condition obtained from the Down-Scaling Simulation System was employed. From the present results, the advection and decay process of wake turbulence affected by the horizontal roll convection currents in sea breeze was observed. And also the comparison to the simulation of wake turbulence with the uniform boundary and initial flow condition, which was set based on the weather observation value (10 minutes average value of wind velocity, direction of the wind) provided by Japan Meteorological Agency was conducted. The comparison confirmed that the more detail behavior of wake turbulence can be obtained with the initial and boundary condition provided by the Down-Scaling Simulation System., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0064672011, レポート番号: JAXA-SP-09-011}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {気象観測とCFD を利用した後方乱気流シミュレーション}, volume = {JAXA-SP-09-011}, year = {2010} }
