Title: EVALUATION OF WIND FORECAST IN NORTHEASTERN BRAZIL IN DIFFERENT
TIMESCALES
wind, climatology, homogeneous regions, trends, forecast.
The Northeast region of Brazil (NEB) stands out in the national scenario of wind energy production, with
523 wind farms installed out of a total of 619 in Brazil. With favorable winds for the production of wind
energy, especially in the second half of the year, there is still room for prospecting and expanding wind
farms, given that there are still states with few or no wind farms installed, as is the case of Alagoas. To
optimize the choice of the best locations for installing/expanding wind farms, wind-related data, such as
predominant direction and speeds at different heights, are increasingly necessary, demanding the most
accurate measurements and estimates of this atmospheric variable possible. In this sense, in this work we
used near-surface wind speed data from the latest version of a high spatial resolution (0.1° x 0.1°) gridded
analysis on a daily scale, made available by Xavier et al. (2022) from January 1, 1961 to July 31, 2020.
Such data will be used for analysis and forecasting, using the canonical correlation analysis technique, in
addition to allowing the identification of homogeneous regions in the NEB, as well as applying statistical
tests to verify trends and homogeneity of time series.
