Abstract:

The objective of this paper was to determine the expected wind speed (km/day) as a function of the daily average values, at various levels of probability, recorded during thirty-eight years (1970-2007) for the city of Mossoró-RN. Based on the Kolmogorov-Smirnov test, we found that the beta distribution can adequately describe the wind pattern, for all months of the year. We found average wind velocity values of 219.0 km/day demonstrating the great possibility of using this meteorological element as an alternative source of energy for the region.
