- •
We assess the effect of turbulence spectral model parameters on wind turbine design loads.
- •
Wind measurements at the Høvsøre site are used to quantify the Mann turbulence model parameters.
- •
The measured turbulence parameters differ from the recommended values in IEC61400-1, ed.3.
- •
We find a significant effect of turbulence model parameters on both extreme and fatigue design loads.
- •
We conclude that case-specific turbulence model parameter values should be used.
