Development of a system for predicting snow distribution in built-up environments: Combining a mesoscale meteorological model and a CFD model

摘要: A system has been developed for predicting snow distribution in built-up environments. This combines a mesoscale meteorological model that predicts precipitation, including snowfall an area, and Computational Fluid Dynamics (CFD) phenomena on building scale. The focuses around buildings, which often leads to disaster snow-related difficulties urban areas. It can be used due snowdrift development area is expected useful design tool city architectural planning snowy regions. paper outlines the examines its performance by comparing results with measured data. patterns, i.e. erosion upwind corners deposition front of behind building, obtained present show good correspondence those from field observation. However, under-predicted decrease depth near building. Further investigations required comprehensively evaluate prediction accuracy are discussed.
