Abstract
A model has been derived for calculating the aggregate effects of stability and the finite height of the planetary boundary
layer upon the long-term mean wind profile. A practical implementation of this probabilistic extended similarity-theory
model is made, including its incorporation within the European Wind Atlas (EWA) methodology for site-to-site application.
Theoretical and practical implications of the EWA methodology are also derived and described, including unprecedented
documentation of the theoretical framework encompassing vertical extrapolation, as well as some improvement to the
methodology. Results of the modeling are shown for a number of sites, with discussion of the models’ efficacy and the
relative improvement shown by the new model, for situations where a user lacks local heat flux information, as well as performance
of the new model using measured flux statistics. Further, the uncertainty in vertical extrapolation is characterized
for the EWA model contained in standard (i.e., WAsP) wind resource assessment, as well as for the new model. Copyright
