Data sets

Doppler wind lidar wind and gust data from FESTVAL 2019/2020 Falkenberg, data version 01 J. Steinheuer, C. Detring, M. Kayser, and R. Leinweber https://doi.org/10.25592/UHHFDM.9758

Short summary

This work analyses a meteorological event, called nocturnal low-level jets (NLLJs), defined as high wind speeds relatively close to the surface. There were positive and negative impacts from NLLJs. While NLLJs increased the mean power production, they also increased the variability in the wind with height. Our results imply that long NLLJ events are also larger, affecting many wind turbines at the same time. Short NLLJ events are more local, having stronger effects on power variability.
