Short summary

Models of wind behavior inform offshore wind farm site investment decisions. Here we compare a newly developed model to another, historically used model based on how these models represent winds and turbulence at two North Sea sites. The best model depends on the site. While the older model performs best at the site above a wind farm, the newer model performs best at the site that is at the same altitude as the wind farm. We support using the new model to represent winds at the turbine level.
