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.

由于山脉和丘陵的尺度很小，风对各种因素的依赖性，例如近地面空气的温度结构，因此很难模拟复杂地形的大气流动。 该奖项将使一组研究人员有机会参加葡萄牙的大型现场活动，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，供数值模拟人员在未来许多年使用，对理解风能、空气污染、航空、污染物扩散和高山战争等重要的边界层流动产生影响。 此外，一些学生将有机会参加该活动，并与国际同行进行互动。Perdigao现场活动是欧洲提高风能生产效率的大型努力的一部分。 该奖项将为这项工作带来一个基础研究部分，重点是研究不同尺度流动之间的相互作用、地形和昼夜热力强迫的影响、山谷/斜坡边界层和涡轮机尾流。 该项目提供的仪器将包括多个激光雷达、系留提升系统、云高计、无线电探空仪系统、风速计和集成移动的剖面系统。
