As wind power grows as an important contributor to the worldwide overall energy portfolio, wind farms will cover increasingly larger surface areas. With the characteristic height of the atmospheric boundary layer (ABL) of about 1 km, wind farms with horizontal extents exceeding 10–20 km may therefore approach the asymptotic limit of ‘infinite’ wind farms, and the boundary layer flow may approach the fully developed regime. Envisioning such large-scale implementations calls for advancements in our understanding of the detailed interactions between wind turbines and the atmospheric surface layer. In the past, a number of studies have focussed on the effect wind-turbine arrays on the WTABL using elements of momentum theory, potential flow, and the superposition of wakes of individual turbines (cf. Lissaman
1979
, and Frandsen
1992
). Several recent studies have focused on such dynamics of Wind Turbine Array Boundary Layers (WTABL) (Calaf et al.,
