Research on renewable energy sources becomes of crucial importance in view of global warming, fossil fuels crises and nuclear power dangers. Wind energy gradually takes bigger part of energy production in Western European countries and is planned to develop further. This process depends on new technologies (size, shape and materials of blades and higher turbines), but also specific meteorological research on vertical wind profile is required. Both the construction and energy production of new more efficient wind turbines are presently impeded by the meteorological parametrizations in the models used. Further, both wind energy assessment models and mesoscale meteorological models implement surface layer wind profile parametrizations (valid up to 50-80 meters) for turbines of height 200-300 meters above ground. Recently published by the applicants analysis suggests improved parametrizations of the wind profile in the lower few hundred meters above ground revealing the importance of the atmospheric boundary layer height. The new wind profile parametrization was tested over flat grassland, flat suburban area and over sea. Still, the parameters that control the wind profile above 100 meters are poorly understood. Further research, both experimental and theoretical, is needed to check applicability limits and to streamline the formulations. The results can be directly implemented in wind power assessment models and mesoscale meteorological models. Deepening the understanding of the processes (wind, temperature and turbulence profiles) within the atmospheric boundary layer has many other important applications, such as atmospheric dispersion for accidental releases, air pollution, parametrizations in climate models, loads on tall buildings, etc. The research will be conducted through experimental campaigns, data analyses and theoretical considerations. Implementation strategy and first applications in existing wind energy assessment models will be done.
