Wind characterisation still suffers from uncertainties regarding the spatial description associated with small-scale wind structures, such as orographic effects. At the same time, the definition of the shape of the vertical wind profile is still based on theories developed from ground-based observations. Thus, improving wind characterisation is crucial to reduce uncertainties in resource assessment and wind turbine design.
To improve the characterisation of extreme winds by combining atmospheric models with satellite and in-situ observations.
Scientific and technical contents
- Methodological developments to extrapolate satellite surface winds at nacelle height.
- Use of observations performed using synthetic aperture radar (SAR) to record the high resolution spatial variability of wind fields and extreme winds, and coupling with wind forecast models.
- Tests in a wave tank fitted with a wind generator to study air-sea interactions during extreme events.
- Extraction of more accurate information from several atmospheric models combined with observations using optimised observation networks.
