TNO report - Observational Analyses of the North Sea Low-Level Jet

As part of the Dutch Offshore Wind Atlas (DOWA) project, analyses were performed on offshore wind measurements to provide enhanced characterisation of the North Sea wind climate. Of particular interest was the spatiotemporal behaviour of the offshore low-level jet (LLJ) – an anomalous wind event that can significantly impact both wind turbine power performance and loading. LLJs are characterised by a maximum in the vertical wind speed profile relatively close to the surface.
