摘要: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 ???? range from 1.474 to 1.607, with yearly value of 1.546 while the seasonal values of the scale parameter 𝑘𝑘 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.
