The study looked at wind patterns in Northeastern Brazil to help estimate wind power accurately. They found that wind speed changes with height and weather conditions, affecting how much energy can be generated. By analyzing data from a wind mast, they discovered that strong winds can override stability effects, improving estimates of wind characteristics. They also developed methods to predict wind speeds at different heights, with one approach working better in rainy seasons but overestimating high winds. The study showed that understanding how wind behaves at different heights is crucial for reliable energy estimates, especially with limited data and lower wind speeds.
