Determining Temperature trends in the Granary Areas of Peninsular Malaysia using Mann-Kendall and Sen’s Slope Estimator

The spatiotemporal dynamics of temperature as well as rainfall have received greater attention from the scientific communities This study analysed temperature variability in the three granary areas of Peninsular Malaysia using descriptive statistics parametric least square regression and nonparametric Mann- Kendall and Sen s slope estimator The study identified significant warming trend in the annual mean maximum temperature in two of the study areas i e Subang Jaya and Kota Bharu Also significant warming trend was detected in the annual minimum temperature and significant increasing trend in some of the monthly maximum and minimum temperatures for all the three stations Also the result reveals spatial and temporal variation in both the maximum and minimum temperature at annual monthly and seasonal scales For the annual scale maximum temperature this study identified a warming trend for the two stations with about 0 014oC per year 1 4oC per 100 year
