The analysis of rainfall behavior, particularly in terms of occurrence, is greatly important in
many areas such as water resource management and agricultural planning. This aim of this
study is to fit various types of probability models including simple geometric, log series as
well as the mixture probability models to describe the distribution of wet spells. Daily rainfall
data of the period 1977 to 2004 and the observed frequency of wet spells data sets for the
period of 1940s to 1976 for each of the eight selected rainfall stations in Peninsular Malaysia
are used in this study. In selecting the best fitting probability model to describe the observed
distribution of wet spells for each rainfall station, chi square goodness-of-fit test is considered.
The findings of this present study revealed that the mixed geometric distribution is the
probability model found to be the most successful in representing the distribution of wet spells
for both periods since all the data sets fitted the model well |
