The performance of wind turbines operating in the wakes of upwind ones within a wind farm is severely impacted by the reduced incoming wind speeds and increase in turbulence intensity. As a consequence, wind energy production is decreased along with an increased dynamic loading applied on the downwind turbines. Therefore, real-time monitoring and o...

The transient wind field during a nonsynoptic wind event (e.g., thunderstorm downburst) presents time-varying mean and non-stationary fluctuating components, and hence is not easy to be reproduced in a conventional boundary-layer wind tunnel with various passive devices (e.g., spires, roughness elements, and barriers). As a promising alternative, t...
