Climate prediction demonstrates that the earth temperature has increased due to increases in concentrations of greenhouse gases. So that led to significant changes in meteorological elements. In this research the effect of climate change on rainfall and temperature at stations of Gorganrood-Gharesoo watershed for the period of 1987-2008 were examined. Daily data output by HadCM 3 and ECHAM 4 under scenarios of climate models using LARS-WG were downscaling and predicted for the period of 2030-2011. The results showed that based on HadCM3, the amount of rainfall 12.6, 3.3 and 3.5% and temperatures as 0.5, 0.3 and 0.31 °C respectively in the scenarios A 2 , B 1 and A 1 B increased compared to the base period. Moreover, ECHAM4 model shows increases in temperature in all three scenarios. However rainfall by -11.6% under scenario B 1 decreased. The results of this research could be used in water resources management planning and agriculture sector.
