The 2-parameter Weibull distribution was used to analyse the wind speed at high-altitude mountain site Chopok, situated in the central part of Nízke Tatry mountains in Slovakia. Analysed wind speed data has been collected over 11 year period (2005–2015) and measured under standard conditions – in the height of 10 m over above ground using calibrated anemometers. Suitability of Weibull distribution was assessed using the coefficient of determination and root mean square error. From the results it is concluded that the 2-parameter Weibull distribution adequately describe the observed wind speed and can be used with acceptable statistical accuracy for prediction the wind speed data at this location.
