Characteristics of the wind regime in Hon Yen island (Phu Yen province) from analysis of NCEP CFSR dataset (1979-2020)

The wind data set of 10 m on the sea surface is provided by meteorological data NCEP CFRS corresponding to 42 years (1979–2020), with hourly frequency. The purpose of this paper is to find the most effective numerical method for the Weibull distribution function for the wind regime in Hon Yen waters based on analyzing and comparing the efficiency of 10 (ten) numerical methods, namely, the empirical method of Justus (EMJ), the empirical method of Lysen (EML), the method of moments (MoM), the graphical method (GM), the Mabchour’s method (MMab), the energy pattern factor method (EPFM), the maximum likelihood method (MLM), the modified maximum likelihood method (MMLM), the equivalent energy method (EEM), and the alternative maximum likelihood method (AMLM). According to the analysis results, the EPFM method is best suited for the wind regimes of January, July and December; MLM method is best suited for February, June, August and September wind regimes; The EML method is best suited for the wind regime in March and October and the EMJ method is best suited for November. The AMLM method often results in inaccurate results in forecasting the wind regime in the Hon Yen area.
