Wind power assessments and predicting wind energy production are important for wind energy studies. Traditional wind models don't account for the wind profile above the surface layer where modern wind turbines are located. Researchers used a long-range wind lidar to measure wind profiles up to 600 meters high. They found that the wind speed predicted by the model was lower than what was actually measured above 100 meters. This underestimation has implications for wind energy production. The researchers suggest a new way to estimate the shape parameter of the wind speed distribution.
