Abstract:
Rainfall is one of the climate elements that is interesting to study in order to reduce the impact caused by extreme rainfall. The method used in analyzing extreme values is Extreme value Theory with a maximum block approach of Generalized Extreme Value. And using the Probability Weighted Moments method in estimating the parameters. The results of this study indicate that December has the longest tail compared to other months, because it has the smallest shape value. The estimation result in December shows the shape value -0.025, location 309.355 and scale 98.959. And the return level results show that December has the greatest probability of occurrence of extreme values because it produces the largest maximum estimated value compared to the others. The maximum estimated values in December for the next 2,3,4,5 and 6 years period are 346,4808 mm, 394,0712 mm, 424,2779 mm, 446,5129 mm, and 464,1209 mm.
