507 Prediction of wind field over a complex terrain with meso-scale model WRF and local wind simulation code NuWiCC(2)

Abstract

The wind predictions around Mt. Akagi with meso-scale model WRF and local wind-simulation code NuWiCC were carried out. Numerical results with WRF suggested that the large-scale spatial structure with an active advection in the vertical direction play a dominant role. In addition, the behavior of predicted wind fields strongly depends on the governing equations used in the numerical model, i.e., the meso-scale model is suitable to predict the such wind fields, while the horizontal wind-field obtained with local-wind simulation code becomes uniform spatially, regardless of inflow condition.
