摘要：
Extreme rainfall may cause problems to the social, environmental and ecology. In this paper, we focused on regional frequency analysis of extremes rainfall based on 3-hourly rainfall records by TRMM 3B42 and raingauge data between 1998-2012 at 30 stations of Peninsular Malaysia, Malaysia. Based on the L-Moments method, we developed the regional extreme rainfall frequency analysis in measuring discordancy, regional homogeneity and the goodness-of-fit test to determine the best regional parent distribution. The Wards method is presented to identify the homogenous regions in Peninsular Malaysia and produce 4 acceptably homogeneous regions that had been tested by the L-Moments method. The results show that the L-Moments method is good in term of performance, simplicity and robustness.
