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.

我的研究计划关注的是了解大气与复杂地形的互动的性质：在山上，山谷和沿山海岸线。提出的研究既涉及进行测量（直接在表面，并且在表面上方遥远），以及对这些区域中大气进行高分辨率的计算机模拟。在进行此研究主题时，将进行许多项目，以解决基本和应用大气科学问题，以及与多学科问题的协作项目。除了进一步了解大气边界层外，这项工作还将针对健康，安全和经济影响（例如：空气污染和森林害虫的运输和分散）解决重要问题；预测海洋，航空和公共用户的风；并估计西部山脉西部冰川及其供水对气候变化的反应。 UNBC和Computecanada的高性能计算设施将用于对西部山脉西部特别感兴趣的几个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值进行比较来验证。高分辨率的模型输出将在多年期间存档，从而使现象学研究仅超过对少数案例研究的分析，并基于高分辨率模型输出来开发合理的统计数据。预计这项研究的结果将导致：更好地了解山松树甲虫侵扰的远程运输；更好地理解未来气候对西部科迪勒拉的冰川质量平衡的影响；对质量风现象的理解；以及改进的预测空气质量和风的方法。
