In the subproject A01, the transition of the turbulent and near-ground Prandtl layer into the more laminar Ekman layer, which has been insufficiently investigated so far, will be studied. This will be based on free field measurements, numerical simulations and wind tunnel measurements. A realistic (reduced) modelling of wind fields, which represents both the turbulent and the laminar properties of both layers, is crucial for a determination of aerodynamic impacts on very large future offshore wind turbines. It also allows capturing new interactions between wind and turbines.

在分项目A01中，将研究湍流和近地面普朗特层向更层流的埃克曼层的转变，这一点迄今尚未得到充分研究。这将基于自由场测量、数值模拟和风洞测量。一个现实的（减少）风场建模，这两个层的湍流和层流特性，是至关重要的空气动力学的影响非常大的未来海上风力涡轮机的确定。它还允许捕捉风力和涡轮机之间的新的相互作用。
