Analysis of Advantages Data on Hijri Year Compared AD Year through Wind Speed Climate Modeling
Downloads
The Gamma and Weibull distribution models were used for modeling wind speed data in the AD years and Hijri years. This study aims to determine the best model for wind speed data using Gamma and Weibull distributions. The research data used is wind speed data in the AD year from January 1999 to March 2019 and the Hijri year 1420-1440 at Tabing Airport, West Sumatera. This study showed that the Gamma distribution model was more suitable for wind speed data in 1420-1440 Hijri year than the Weibull distribution. This is shown from the results of the AIC Aikake's Information Criterion) test, which shows that the AIC value for the Gamma distribution is smaller than the AIC test results on the Weibull distribution value, while the Gamma distribution AIC value for the Hijri year data is smaller than the AD year data for the Gamma distribution
