Analysis of Climate Variability and Trends in The Context of Climate Changes: Case Study in Terengganu

Abstract

Uncertainty of climate extreme nowadays causes an alteration in the local climate trend and variability. Terengganu, Malaysia recorded series of extreme drought and flood events throughout a year affected by North-East monsoonwhich will change the next climate pattern. Thus, itwill be affectingthe long-term planning and sustainability that related to the water resources in the long-term. The objective of this study was to analyse the trend changes of rainfall and temperature at Kuala Terengganu, Malaysia due to climate changes impact. The trends changes were analysed usingMan-Kendall and Sen’s Slope. The climate projection result shows the annual mean temperature is expected to have decreasing trend until end of century. However,Mar to June are expected to bit higher than historical reach to 29oCby RCP8.5. Then it will be dropped to 24oC (-5% from historical) during Northeast monsoon. Consistent to the annual rainfall, it was expected to have increasingtrendover time. The highest increasing trendwas expected to occur on Nov toDec more than40% by RCP8.5.
