| Abstract | Having a better understanding of how extreme rainfall events change the future climate is vital due to its large impact on society. One of the factors that need to be considered is atmospheric temperature, where according to Clausius-Clapeyron relation, extreme rainfall is expected to increase at the rate of 7% per degree of warming. This paper investigates the trend of extreme rainfall by analysing observational data in Peninsular Malaysia and comparing it against regional climate models (RCM) simulations of historical climate. The study showed that RCM is driven by EC-EARTH generally performs better in simulating the trend of extreme rainfall with surface air temperature in Peninsular Malaysia compared to the model driven by IPSL-CM5A-LR. Furthermore, the study showed that extreme rainfall is decreasing with the increase of temperature at a large area across Peninsular Malaysia. |
