Atmospheric general circulation models are developed for simulation of current climate of the earth and are able to predict the earth's future climate change. In this paper, the performance of GFDL CM2.1, CSIRO Mk3 and HadCM3 AOGCMs were assessed and evaluated in the study of the climate change effects on temperature and precipitation in Taleghan basin. The results show that HadCM3 model in comparison with CSIRO Mk3 and GFDL CM2.1 models has indicated the better performance in this region. http://pubs.sciepub.com/ajcea/6/3/1/ajcea-6-3-1.pdf Atmosphere General Circulation Models AOGCM CSIRO Mk3 HadCM3 Climate Change Taleghan Region
