Wind speed modeling using Weibull distribution: A case of Liptovský Mikuláš, Slovakia

Abstract

In the present paper, the Weibull distribution is used to analyse the wind speed data of Liptovský Mikuláš-Ondrašová (49°05′52″ N, 19°35′32″ E), situated in northern Slovakia. Analysed wind speed data were collected over the 11-year period (2005-2015) and they were recorded three times a day. The results show that the seasonal values of the shape parameter k range from 1.474 to 1.607, with yearly value of 1.546 while the seasonal values of the scale parameter c range from 2.488 to 3.010 m/s, with yearly value of 2.726 m/s. We find out that according to the coefficient of determination and root mean square error, the Weibull distribution performs well in fitting the wind speed data.
