In this paper, for the first time, the upper truncated inverse Weibull (UTIW) distribution is proposed for modeling wind speed data. Since there is a upper limit for empirical wind speed data, this data can be represented by using the UTIW distribution. In this study, the UTIW distribution is introduced and some of its statistical properties are studied. Then, the parameters of this distribution are estimated by using different methods. Simulation studies for these estimators are presented. In addition, the mentioned distribution performance is tested on real wind speed data of Ardabil province in Iran. Based on the results of the analysis, it is found that the presented distribution in this study for modeling wind speed data is more appropriate than recently introduced distributions. Finally, this distribution can be used as an alternative model for evaluating wind speed data
