Abstract

This research analyses the daily average wind speed time series of ten Transcarpathian meteorological stations in the period from 1991 to 2000 with the help of statistical methods. We approximated the empirical frequency distribution of measured daily average wind speeds by means of theoretical distributions. The results of the fitting test showed that among the applied theoretical distributions, irrespective of the orographic environment, Weibull distribution proves to be the most suitable. However, fitting of the Weibull distribution depends on the methods of determining the k and c parameters. By means of the best fitting parameters, we worked out the distribution density function and some of its indices at the altitude of 80 m contrary to the anemometer altitude that is often the hub height of industrial wind turbines, thus estimating the area’s wind conditions from the point of view of wind energy utilization.
