Statistical Distribution of Rainfall in Kurdistan-Iraq Region

Abstract


Study the statistical distribution for rainfall is important to know the behaviour of the rainfall series and to know the most frequently rainfall amount in each month. Five statistical distribution were applied on Sulaimani, Erbil and Duhok rainfall series for the period (1941-2017) except Duhok (1944-2017). These distributions were Gamma(3P), Weibul(3P), Earlang (3P), Normal and General extreme value. Kolmogrove-Semirnov, Anderson-Darling and Chi-Square goodness of fit test were used to know the best fit distribution from these five distributions.

Keywords


Gamma, Weibul and Earlang distribution, Kolmogrove-Semirnov, Anderson-Darling and Chi-Square test
