  The physical growth of wind energy over several decades, caused a
re-investigation mesoscale effects on wind plant dynamics. At a large scale
operation, understanding the interactions between atmospheric phenomena and
wind plant wakes is crucial to improving models. Within a wind plant, wakes are
generated by individual turbines and the summation of individual wakes is the
global plant wake. In both cases, the dynamics are sensitive to atmospheric
conditions; one of interest to wind and atmospheric scientists is the Coriolis
force. Current research noted spatial and temporal influences on the global
plant wakes caused by the Coriolis force. Due to the presence of wind veer in
the atmospheric boundary layer, field research is notoriously difficult. As a
result, investigations have been lead by numerical simulations. This proved
helpful for initial queries, established the significance of the Coriolis force
as a non trivial parameter of wind plant dynamics. This works presents a novel
experimental study of the impact of the Coriolis force on the dynamics of a
scaled wind plant. The experiments show that for a single turbine the wake
deflection is insignificant. Additionally, the results show that the global
plant wake deflects in the anti-clockwise direction in the Northern hemisphere.
The outcomes of this work yield unique experimental methods for research in
wind energy, and provide a new basis for the fundamental dynamics of a wind
plant under influence of the Coriolis force for future wind plant models
causing influence on the global expansion of wind energy.
