My research program is concerned with understanding the nature of the atmosphere's interaction with 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 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; and estimating the response of glaciers in the western Cordillera, and the water they supply, to a changing climate. High Performance Computing Facilities at UNBC and ComputeCanada will be used to conduct continuous high-resolution simulations of the atmosphere over several areas of particular interest in the western Cordillera. 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. Results of this research are anticipated to lead to: better understanding of the long-range transport of mountain pine beetle infestations; a better understanding of the effects of future climate on glacier mass balance in the western Cordillera; an understanding of the Qualicum wind phenomenon; and improved methods of forecasting air quality and winds.

我的研究项目关注的是了解大气与复杂地形相互作用的性质：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)，也包括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。除了增进对大气边界层的基本了解外，这项工作还将处理涉及健康、安全和经济影响的重要问题，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；估计科迪勒拉西部冰川及其供应的水对气候变化的反应。UNBC和ComputeCanada的高性能计算设施将用于对科迪勒拉西部几个特别感兴趣的地区的大气进行连续的高分辨率模拟。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。这项研究的结果预计将导致：更好地了解山松甲虫侵扰的远距离转移；更好地了解未来气候对科迪勒拉西部冰川物质平衡的影响；了解Qualicum风现象；以及改进空气质量和风的预报方法。
