In the past decades, there has been worldwide demand for renewable energy, leading to a dramatic expansion in all its sectors, with a significant fraction generated by wind. Before the construction of a wind farm, it is critical to evaluate the wind speed condition of the location. Since the power is the cube function of wind speed, minor speed changes can cause large deviations in the output power. Moreover, the wind varies both geographically and temporally over a wide range of scales. Therefore, an accurate assessment of the wind resource for a proposed site is highly essential and is considered of paramount significance for a wind project to be successful. The assessment also helps to the selection of wind turbines and their layouts.
