The OSU global atmospheric general circulation model (AGCM) has been coupled to a 60-m deep mixed-layer ocean model to simulate the equilibrium seasonal climatic changes induced by a doubling of the CO{sub 2} concentration. Simulations with CO{sub 2} concentrations of 326 ppmv (1{times}CO{sub 2}) and 652 ppmv (2{times}CO{sub 2}) were performed using an accelerated integration procedure for 45 solar cycles followed by the normal unaccelerated integration procedure for 24 and 16 solar cycles (years), respectively. Averages were then obtained over the last 10 yr of each simulation and were analyzed in terms of the annual-mean climate and the annual cycle of climate, the latter defined as the departure of the monthly or seasonal mean from the corresponding annual mean.
