COSTA, Gabriel Brito and LYRA, Roberto Fernando da Fonseca. Wind patterns analysis in Alagoas State. Rev. bras. meteorol. [online]. 2012, vol.27, n.1, pp.31-38. ISSN 0102-7786. http://dx.doi.org/10.1590/S0102-77862012000100004.
Aiming to evaluate areas with good prospects for harnessing wind power, the patterns of wind speed and direction measured at anemometric towers within the Atlas Eólico e Disseminação da Tecnologia Eólica no Estado de Alagoas project were compared for the period from 12/2007 to 11/2008, at Alagoas State. We analyzed three distinct regions: Coast, Agreste and Sertão. The patterns with higher average wind speeds were in the Agreste regions (7.1 ± 1.2 ms-1 monthly) followed by Sertão (6.8 ± 0.9 ms- 1 monthly) and by Coast (5.3 ± 0.8 ms-1 monthly). The regularity of the wind speed and the low variability of wind direction make Alagoas be a great option for the installation of wind turbines.
