Atmospheric flows over complex terrain

我的研究项目关注的是了解复杂地形地区的风的性质：越过山脉，穿过山谷，沿着多山的海岸线。拟议的研究既包括进行测量(直接在地表进行测量，也包括在地表上方进行远程测量)，主要涉及对这些地区的大气进行高分辨率的计算机模拟。在开展这一研究主题时，将开展若干项目，以解决大气科学的基本问题和应用问题，以及涉及多学科问题的协作项目。除了促进对大气边界层的基本了解外，这项工作还将解决与健康、安全和经济影响有关的重要问题，例如：空气污染和森林病虫害的运输和扩散；为海洋、航空和公众用户预报风；评估易受大风影响的森林地区，以期管理森林，最大限度地减少木材被吹倒。加拿大不列颠哥伦比亚省中心由CFI/BCKDF资助的新的高性能计算设施将用于对不列颠哥伦比亚省中部内陆和沿海地区几个特别感兴趣的地区的大气进行连续的高分辨率(水平网格间距为1至3公里)模拟。模型输出将通过与观测结果的比较来验证。高分辨率的模型输出将被存档多年，使现象学研究能够超越仅对少数案例研究的分析，并根据高分辨率的模型输出制定合理的统计数据。这项研究的一些成果预计将导致：改进空气质量和风的预报方法；更好地了解山松甲虫侵扰的远距离转移；森林资源管理人员将利用信息更好地规划森林采伐和处理办法，以尽量减少树木被吹倒造成的经济损失和生态破坏；更好地了解未来气候对西部地区冰川质量平衡的影响。

My research program is concerned with understanding the nature of wind flow in areas of complex terrain: over mountains, through valleys, and along mountainous coastlines. The proposed research involves both making measurements (directly at the surface, and remotely above the surface), and mainly involves conducting high-resolution computer simulations of the atmosphere in these areas. In conducting this research theme, a number of projects will be undertaken to address both basic and applied atmospheric science questions, as well as collaborative projects with multidisciplinary questions. In addition to furthering basic understanding of the atmospheric boundary layer, this work will address important questions with health, safety, and economic implications such as: transport and dispersion of air pollution and forest pests; forecasting winds for marine, aviation and public users; assessing areas in forests prone to strong winds with a view to managing forests to minimize timber blow down. The new CFI/BCKDF-funded High Performance Computing Facility at UNBC will be used to conduct continuous high-resolution (horizontal grid spacing of 1 to 3 km) simulations of the atmosphere over several areas of particular interest in the British Columbia central interior and coastal zone. Model output will be validated through comparisons with observations. Model output at high resolution will be archived for a multi-year period, allowing phenomenological research to go beyond analysis of only a few case studies, and to develop reasonable statistics based upon the high resolution model output. Some results of this research are anticipated to lead to: improved methods of forecasting air quality and winds; better understanding of the long-range transport of mountain pine beetle infestations; information for forest resource managers to use in better planning forest harvesting and treatments to minimize economic loss and ecological damage from tree blow down; and a better understanding of the effects of future climate on glacier mass balance in the western cordillera.
