Abstract
  • The aim of this work is gaining further understanding of the structure of the marine atmospheric boundary layer (MABL) and its interaction with the synoptic scale forcing. A possible application is to simulate mean and turbulent spatial/temporal structure of the marine boundary layer to optimise the structural design of offshore large wind turbines. Large-Eddy Simulation (LES) have been performed and compared with offshore experimental data collected during the LASIE campaign performed in the Mediterranean in Summer 2007. A series of simulations are performed and the results have been compared against experimental soundings. Results show that the LES with a force restore nudging technique outperforms the simulations without force-restore nudging for all the fields. This demonstrates that incorporating changes in the large-scale features into the model is necessary in order to provide a realistic evolution of the meteorological fields at local scale. Thus, LES appears as a promising technique to be applied to the simulation of offshore cases and particularly appropriate for wind energy applications. (literal)
