Abstract

Ths study aims to investigate the daily rainfall pattern over a 39 year period (1 970-2008) using data from 50 selectedramfall statiom. The trends and spatial pattern of the daily rainfall data in Penimular Malaysia based on seasonal rainfall indces. The stom behaviors comprising of the Arrivals Stom (AS), the Number of Raincells (NR), the Raincells Intemity (RI) and the Raincells Duration (RD) will be used to analyze during the monsoon seasom. Due to the limited number of stations, the geostatistical method of ordinaq kriging is used to compute the values of propehes of stom and to map their spatial distribution. The findings of this study indicate that there were differences in spatial distribution of arrival stom over Peninsula during both seasons with highest rate arrival stom over the East compared to other regions during South West Monsoon (SWM). In contrast the rate arrival stom significantly decreasing over the East regions during Noh East Monsoon (NEM). The stom is more common inNEM season than SWM season. In tems of number of raincells, it can be concluded that the spatial distribution rate number of raincells during NEM season hgher than SWM season. In contrast the spatial distribution the rate raincells intensity during NEM seasons lower than SWM season. However, no significant differences in raincells duration during both seasom over Peninsula. This finding explains the occurrence of a large number of floods and soil erosiom would more likely occur in the NEM, especially in the South West and East region. Therefore, precautionaq measures should be taken earlier to prevent any massive destruction of propedy and loss of life due to the hazards.
