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.

由于山脉和山丘的小尺度以及风的依赖对各种因素，例如地面附近的空气温度结构，因此很难模拟大气流过复杂的地形。 该奖项将使一群研究人员有机会参加葡萄牙的大型现场活动，并通过部署大量工具来补充实验。 该项目应导致一个数据集，该数据集将在未来多年中使用数字建模者使用，并影响了解边界层流对风能，空气污染，航空，污染物分散和高山战很重要。 此外，许多学生将有机会参加竞选活动并与国际同事互动。佩迪戈·菲尔德（Perdigao Field）运动是提高风能生产效率的巨大努力的一部分。 该奖项将为这项工作带来基础研究的组成部分，重点是研究不同尺度的流量，地形和昼夜热强迫的影响，山谷/坡度边界层和涡轮机唤醒之间的相互作用。 该项目提供的仪器将包括多个激光圈，一个束缚起重机，天花板，辐射系统，启示仪和OU夹具集成的移动分析系统。
