The area offshore the Nagasaki Prefecture, Japan, is a promising area for offshore wind farm. The purpose of this study is the accurate modelling of typhoon wind fields as input variables for the design of offshore wind farms. To ensure the high accuracy of typhoon wind and derived wave and hydrodynamic conditions, a hybrid approach using global reanalysis data and local parametric typhoon modelling is adopted. The hybrid wind fields for two typhoons, Maysak and Haishen, that in 2020 passed offshore Nagasaki Prefecture, are validated against observed wind data. The results show that the proposed hybrid methodology allows for a more accurate representation of extreme wind conditions and consequently of derived wave and hydrodynamic conditions, leading to reduced risks in the design of offshore structures.
