将大气多尺度数值模型与边界层风洞相结合，形成了一种强大的混合工具，用于评估复杂地形下的风力发电场址。风洞用于指导以可控、可复制的方式改进、校准和验证中性热稳定性的数值模型，并改善在最恶劣的地形（如陡峭的悬崖和悬崖）中数值模型失去精度的风力场址评估。该数值模型处理了热分层流和地球自转产生的科里奥利力，这超出了风洞的能力，除了最恶劣的地形外，它可以准确地评估所有地形。通过参数分析，为风洞试验方案提供指导。混合数值/风洞工具提供了独特的见解，并作为其他常用风力发电评估工具的重要补充，但需要进一步发展才能充分发挥其潜力。未来的工作将包括现场测量，这是验证过程的重要组成部分
An atmospheric, multi-scale numerical model is combined with a boundary layer wind tunnel to form a powerful hybrid tool for evaluating wind power sites in complex terrain. The wind tunnel serves to guide the refinement, calibration, and validation of the numerical model for neutral thermal stability in a controlled, reproducible manner, and to improve wind power site assessments in the most severe terrain such as steep escarpments and cliffs where the numerical model loses accuracy. The numerical model treats thermally stratified flow and the Coriolis force generated by Earths rotation, which are beyond the capability of the wind tunnel, and can assess all but the most severe terrain with accuracy. Through parametric analysis, it also serves to guide wind tunnel testing protocols. The hybrid numerical/wind-tunnel tool provides unique insights and serves as a significant complement to other wind power assessment tools in common usage, but requires additional development to reach its full potential. Future efforts will include field measurements as a vital part of the validation process
