Abstract
The PVPN project (Previsão do Vento em Parques Eólicos no Nordeste Brasileiro “Wind forecast for wind farms in the Brazilian Northeast”) has been made aiming to developing a methodology for the prediction of short and medium-term wind energy in wind farms, proper Brazilian Northeast. This paper presents results from an intensive campaign, which, wind velocity and micrometeorological measurements including turbulence are made. Estimates made by the WRF model for the wind velocity were compared with friction velocity and the fluxes (sensible heat and latent heat). The results showed that the model represented well the daily cycles of the four variables with correlation coefficients between 0.79 and 0.94. The estimation of the wind velocity were very good with a difference of only 10.55%. The estimate of the remaining variables was bad to reasonable.
