雪崩对多雪地区的人类活动有很大影响。利用风洞技术预测建筑物周围的积雪已经进行了许多实验研究。然而，在某些情况下，很难满足雪堆风洞研究的相似性要求。此外，风洞设备对许多规划者和设计师等来说并不容易获得。因此，预测风环境和风雪漂移的数值方法有望成为多雪地区建筑设计和城市规划的有用工具。本研究应用计算流体动力学(CFD)和计算机图形学(CG)技术，对日本新泻县长冈市某建筑群周围的风环境和积雪进行了预测。
Snowdrift significantly affects human activities in snowy regions. Many experimental studies have been carried out using wind tunnel technique to predict snowdrift around buildings. However, it is very difficult in some cases to satisfy the similarity requirements for wind tunnel studies on snowdrift. Furthermore, wind tunnel equipment is not readily available to many planners, designers, etc. Thus, a numerical method for predicting wind environment and snowdrift is expected to become a useful tool for architectural design and city planning in snowy regions. In this study, CFD (Computational Fluid Dynamics) and CG (Computer Graphics) techniques are applied to the prediction of wind environment and snowdrift around a building complex in Nagaoka City, Niigata Prefecture, Japan.
