Due to the rapid growth of computer resources, recently, the boundaries between mesoscale meteorological models and computational fluid dynamics (CFD) models are overlapping; namely, there are now some examples of very high-resolution mesoscale meteorological simulations and some examples of CFD simulations that deal with very large computational domains. As the next phase of such simulation studies, attempts are being made to merge mesoscale and CFD models. In this study, we attempt to merge the Weather Research and Forecasting (WRF) model and a Large-eddy simulation (LES) model using turbulent inflow generation method for analysis of strong winds over urban areas.
