How long need a met-ocean simulation be to obtain the climatology at a potential wind-farm site?

Barstad et al. (2012) downscale four future global climate model (GCM) runs under the A1B scenario (moderate emissions), with bias-corrected sea-surface temperature (SST). The study points to a weak decline in wind-energy potential over the North Sea over the next 50+ years. Thus it is not necessary to address anthropogenic climate change in the assessment of wind energy at the site of a potential wind farm in this region. Read more

 

How may a downscaled model climatology best be post-processed for use by research and user partners?

The time-series outputs of the models comprise a complete climatology, but work is nonetheless underway to obtain outputs in more economical statistical forms. End-user interest may, for example, lie in the return times of extreme events or the joint distribution of key variables. Knowledge of the co-distribution of hub-height wind speed and direction at the site of a potential wind farm, and the associated wind rose, is necessary to determine how turbines should be laid out. To predict wake effects and energy yields, a hub-height turbulence intensity, vertical shear and stability parameter may be appended to the list of necessary distribution variables. Read more
