Conclusions • CNRM-CERFACS.CNRM-CM5 shows consistent results over the nino3.4 region during 1961-2005 • Nino 3.4 shows negative correlation with precipitation in the study region. For the period 1981-2005, the negative correlation is stronger compared to 1961-1980. • Over the study region, observed data shows that monsoon rainfall is suppressed during the El Nino event and enhanced during the La Nina years, this pattern is not same in the model. • Surface temperatures over the Nino 3.4 region shows a clear increasing trend in the future (2056-2100) • RCP8.5 shows increase in temperatures over the study region, the increase is higher in the northern areas. The model shows increase in precipitation over the major part of the country, but decrease in the northern parts.
