. In this article the aeroelastic loads on a 10 MW turbine in response to extreme events (low-level jet, shear, veer and turbulence intensity) selected from a year-long large-eddy simulation (LES) on a site at the North Sea are evaluated. These events are generated with a high-fidelity LES wind model and fed into an aeroelastic tool using two different aerodynamic models: a model based on blade element momentum (BEM) and a free vortex wake model. Then the aeroelastic loads are calculated and compared with the loads from the IECstandards. It was found that the loads from all these events remain withinthose of the IEC design loads. Moreover, the accuracy of BEM-based methodsfor modelling such wind conditions showed a considerable overpredictioncompared to the free vortex wake model for the events with extreme shearand/or veer.
