| Research Abstract |
In this study, we have developed a numerical approach of wind variation over urban areas by taking into account the effects of urban turbulence and meteorological fields. This approach uses the outputs of a high-resolution meteorological model as the inputs of a large-eddy simulation(LES) model. The proposed approach was applied to cases of typhoons and extra-tropical cyclones that spawned significant wind gusts over the Tokyo business district. It was demonstrated that the proposed approach of coupling a meteorological model and an LES model is able to quantitatively estimate the intensity of wind gusts over the urban area. This new approach will be used for applications to solve problems related to natural disasters, environments, and emergency responses.
