Collaborative Research: Perdigao: Multiscale Flow Interactions in Complex Terrain

由于山脉和丘陵的小尺度，以及风对各种因素的依赖，通过复杂地形的大气流动很难模拟，例如地面附近空气的温度结构。这一奖项将允许一组研究人员有机会参加在葡萄牙的大型实地活动，并通过部署大量仪器来补充实验。该项目应该产生一个将在未来多年被数值建模人员使用的数据集，并对了解边界层流动对风能、空气污染、航空、污染物扩散和高山战争具有重要影响。此外，一些学生将有机会参与这项活动并与国际同行互动。Perdigao现场活动是欧洲提高风能生产效率的大规模努力的一部分。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的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迹。该项目提供的仪器将包括多个激光雷达、系绳提升系统、Ceileter、无线电探空仪系统、风速计和OU CLAPS集成移动剖面系统。

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.
