摘要：Wind energy is now one of the most promising energy sources of the world for being clean and abundant. The study of phenomena that are related to changes in atmospheric circulation, such as El Ni.o, are extremely important for its ability to affect wind generation. In order to explore the possible effect of such phenomena in the winds of the Northeast region of Brazil, a statistical analysis to quantify this effect through the model Generalized Autoregressive Score (GAS) is performed. This allows the modeling of time series for different probability distributions. Thus, the GAS is applied to the wind speed series from the Gamma distribution. The model results showed that El Ni.o has influence on the behavior of the wind, even though it is small in magnitude.
