Abstract
Potential evapotranspiration (PET) plays a prominent part in hydrologic water cycle which is responsible for the water from the Earth's surface travel back to the atmosphere. Climate change brought contradictory changes in PET which led to the inconsistency of PET trend globally. Hence, the present study carried out the trend of potential evapotranspiration using meteorological data from 7 different meteorological stations located in Peninsular Malaysia. Mann-Kendall and Sen's slope estimator tests were employed in this article for PET trend analysis. Bayan Lepas experienced significant increasing trend for both FAO 56-Penman Monteith and Mahringer models during Southwest monsoon. For Mahringer model, significant increasing trends were observed at Ipoh and Pulau Langkawi stations during Northeast and inter monsoon 2, respectively. There were only a few meteorological stations experienced decreasing trend throughout the period. Although the combinations of increasing and decreasing PET trends were observed, it can be highlighted that majority of the PET time series exhibited increasing trend in Peninsular Malaysia.
