CCC-EQ

This experiment was performed in Canada in 1989 using the Canadian Climate Centre's T32 high resolution 10-layer atmospheric GCM, coupled to a mixed-layer ocean. The horizontal resolution of the model is approximately 3.7 deg. latitude by 3.75 deg. longitude. The results are from an equilibrium experiment reported in Cubasch and Cess (1990), but discussed more fully in Boer et al. (1992). The experiment is widely referred to as "CCC" or "CCCEQ". We acquired the results from this experiment in May 1993 directly from Norm McFarlene at the CCC in Toronto. The change fields used in SCENGEN are calculated as the difference in climate between the 10-year means of the control (1xCO2) and perturbed (2xCO2) simulations. The model has a climate sensitivity of 3.5degC and a global precipitation sensitivity of 1.1% per deg Celsius of warming.

Mean monthly precipitation pattern correlation coefficient = 0.63
