The presented works aim at proposing a methodology for the simulation of offshore wind conditions using CFD. The main
objective is the development of a numerical model for the characterization of atmospheric boundary layers of different
stability levels, as the most important issue in offshore wind resource assessment. Based on Monin-Obukhov theory, the steady k-ε Standard turbulence model is modified to take into account thermal stratification in the surface layer. The validity of Monin-Obukhov theory in offshore conditions is discussed with an analysis of a three day episode at
