Preliminary investigations into the curvature problem in extreme wind statistics

For the assessment of the Hydraulic Boundary Conditions (HBC), information is required on wind conditions over open water areas, pertaining to return periods up to thousands of years. In earlier assessments of the HBC, a wind modelling concept was developed to provide adequate estimates of the required information. The aim of the present study was to gain more insight in the curvature problem by means of brief analyses into some physical and statistical assumptions in the wind modelling concept that is applied in the etermination of potential wind series and in the earlier assessments of the HBC.
