Atmospheric flow through complex terrain is difficult to simulate due to the small scales of mountains and hills and the dependence of wind on a variety of factors, such as the temperature structure of the air near the ground. This award will allow a group of researchers the opportunity to join a large field campaign in Portugal and to supplement the experiment by deploying a large number of instruments. The project should result in a data set that will be used by numerical modelers for many years to come, with impacts on understanding boundary layer flows important to wind energy, air pollution, aviation, contaminant dispersion and alpine warfare. In addition, a number of students will have the opportunity to participate in the campaign and interact with international colleagues.The Perdigao field campaign is part of a large European effort to improve the efficiency of wind energy production. This award will bring a basic research component to the effort, with a focus on studying interactions between flows of different scales, effects of topographic and diurnal thermal forcing, valley/slope boundary layers and turbine wakes. Instrumentation provided by this project will include multiple Lidars, a Tethered Lifting System, ceilometer, radiosonde system, anemometers, and the OU CLAMPS integrated mobile profiling system.

由于山地和丘陵的小尺度以及风对地面附近空气温度结构等多种因素的依赖，大气在复杂地形中的流动难以模拟。该奖项将使一组研究人员有机会参加在葡萄牙进行的大型实地活动，并通过部署大量仪器来补充实验。该项目将产生一个数据集，将在未来许多年被数值建模者使用，对理解边界层流动产生影响，这对风能、空气污染、航空、污染物扩散和高山战争都很重要。此外，许多学生将有机会参与活动并与国际同事互动。Perdigao油田的活动是欧洲提高风能生产效率的一项重大努力的一部分。该奖项将为该项目带来基础研究内容，重点研究不同尺度气流之间的相互作用、地形和日热强迫的影响、山谷/斜坡边界层和涡轮尾迹。该项目提供的仪器将包括多个激光雷达、系留提升系统、测高仪、无线电探空系统、风速计和OU CLAMPS集成移动剖面系统。
