Abstract
A terrain description model is established for the Risoe site through a WA{sup s}P computation. Mean wind profiles for eight wind direction sectors are compared with the model boundary profiles. Wind data from the 72/76 m recording level of the Risoe mast are updated, including identification of missing and erroneous data. The wind atlas procedure (``the double extrapolation method``) is applied to extrapolate Risoe data to open-water conditions 10 m above mean sea level. Three different extreme value distributions are applied to the extrapolated storm data - two of which are based on the annual maximum (AM) method, and one on the peak-overthreshold (POT) method. T-year estimates including standard error estimates are provided. Finally, a verification is performed by comparing extrapolated storm data with corresponding measured wind data form the Dan and Gorm fields in the North Sea. A high correlation is found for severe storms from the west. A significantly lower correlation is found for moderate and easterly storms. (au) (29 tabs., 29 ills., 59 refs.)
