The energy sector in Brazil faces challenges with regards to climate change as well as energy security. As renewable sources such as wind, solar, and hydropower expand, it becomes crucial to understand the resources and their variations over time to assign a generation capacity credit for long-term energy planning. The improvement of wind resource knowledge by the Energy Research Company (EPE) is a continuous process. Studies based on the Wind Measurement Monitoring System (AMA) are particularly important as they provide detailed information about the wind behavior in the Northeast and South regions of Brazil, specifically where the winning wind energy projects are located. As the wind source gains importance in the national energy matrix, it is necessary to better understand its behavior regarding availability in time and space, and whether its behavior will continue to be consistent with the historical data or if there will be changes resulting from climate change. Therefore, a study that verifies the behavior of the wind source in relation to climatic aspects, in global, mesoscale, and microscale, is of great relevance.
