Development of Regional Climate Model (RCM) for Cameron Highlands based on Representative Concentration Pathways (RCP) 4.5 and 8.5

Development of local climate is important for hazard assessment. Cameron Highlands was chosen as study area (longitude from 101°21’ to 101°30’ and latitude 4°19’ 4°37’) downscaling. This paper presents the work downscaling techniques regional model (RCM) development. The second-generation Canadian Earth System Model (CanESM2) based on representative concentration pathways (RCP) 4.5 8.5 applied develop period 2020-2100. climatic parameters were temperature (maximum minimum) rainfall. simulated RCMs are then analysed using statistical reliability including Pearson correlation coefficient, linear regression, root mean square error (RMSE) probability density function (PDF). result showed that maximum, minimum temperature, rainfall most likely follow RCP scenario. Precipitation threshold occurrence flood event estimated intensity duration frequency (IDF) relationship generated by maximum precipitation. Return two years four hours used estimation convective. daily be 11.3 mm/hr.
