Parameter for forecasting of offshore wind farms — •Jörg Bendfeld and Stefan Balluff — Universität Paderborn, Paderborn, Deutschland

Data from operational offshore wind farms is only available over a short time period. Consequently, it is difficult to extrapolate current data to future deployments. The alternative approach is to estimate wind climate using wind speed data from met masts like FINO I, II and III or the met masts Amrumbank West, Arkona Becken Südost and climate model data like MERRA. There are very few stations that record offshore wind speed and climate. Offshore wind speed, especially in areas that are not close to land, is not subject to many of the spatial factors that influence changes in wind speed onshore; as a result is likely to be more homogeneous over larger areas. The Fetch is important to keep in mind. Predicting the short term wind speed and the resulting energy is of high importance. The chosen meteorological and geographical parameters are very important to improve the forecast/nearcast. Among several parameters the trend of wind speed, wind direction, thermal layering and pressure are important.
