| Abstract | Wet zone of Sri Lanka has been experiencing influences of climate change, in terms of changed rainfall patterns and temperature increases. This research projects rainfall scenarios for the future periods 2030s, 2050s and 2080s for the wet zone of Sri Lanka by considering 05 different stations using BCC CSM 1.1, CC SM 4 and MI ROC 5 GCMs. Data were downscaled using linear scaling bias-correction method and were analyzed with respect to RCP 8.5 and RCP 4.5. The results show that GCMs agree better at lower elevations. Coastal and lowland areas show an increase of 20-21% and the highlands show a decrease of about 3% in annual rainfall. Wettest month changes from October to November until 2050s. It will change to May in 2080s under RCP4.5. Under RCP8.5, the dry months are predicted to be drier in the future. Overall, the rainfall in wet zone is predicted to increase in the future. The period with least rainfall changes from North East Monsoon to 1st Inter Monsoon, while the highest contribution remains with the South West Monsoon. The 1st Inter Monsoon shows a decrease in rainfall ranging from 19-28% in the future scenarios. In the other rainfall periods, the increase ranges from 12-34% for different RCPs. |
