摘要

We have conducted LES (Large Eddy Simulation) simulation, focusing on local heat environment in the urban area. For estimating the reference absolute values (wind velocity and temperature) of LES, we proposed the computational model for hybrid method of LES and meso-scale meteorological model (MM5), and this computational model was validated by comparing the results of LES with field measurement data. Also, we clarified that the heat convection as a result of mixing is active vertically and the high temperature region is recognized even at a high position in a large cavity formed behind dense tall buildings, and we showed that the hybrid method is a powerful tool for predicting of the wind turbulence and the heat environment in the urban area.
