Atmospheric flows over complex terrain

我的研究项目是关于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。拟议中的研究包括进行测量（直接在地表和远程在地表以上），主要包括对这些地区的大气进行高分辨率的计算机模拟。在进行这一研究主题时，将进行若干项目，以处理基本和应用大气科学问题，以及涉及多学科问题的合作项目。除了进一步加深对大气边界层的基本了解外，这项工作还将解决具有健康、安全和经济影响的重要问题，例如：空气污染和森林害虫的运输和扩散；为航海、航空及公众提供风向预报；评估易受强风影响的森林地区，以期管理森林，尽量减少木材被刮倒。CFI/ bckdf资助的新高性能计算设施将用于在不列颠哥伦比亚省中部内陆和沿海地区的几个特别感兴趣的地区进行连续高分辨率（水平网格间距为1至3公里）的大气模拟。将通过与观测值的比较来验证模型输出。高分辨率的模型输出将存档多年，允许现象学研究超越仅对少数案例研究的分析，并根据高分辨率模型输出开发合理的统计数据。预计这项研究的一些结果将导致：改进预测空气质量和风的方法；更好地了解山松甲虫侵染的远距离迁移；为森林资源管理人员提供资料，以便更好地规划森林采伐和处理，尽量减少树木被砍伐造成的经济损失和生态破坏；以及更好地了解未来气候对西部科迪勒拉冰川物质平衡的影响。

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.
