BMRC-EQ

This experiment was performed in Australia in 1991 using the Australian Bureau of Meteorology Research Centre's R21 9-layer atmospheric GCM, coupled to a mixed-layer ocean. The horizontal resolution of the model is approximately 3.2 deg. latitude by 5.6 deg. longitude. It is an equilibrium experiment reported in Gates et al. (1992) and Colman and McAvaney (1995) and is referred to as "BMRC". We acquired the results from this experiment in 1994 from Brian McAvaney at the BMRC in Melbourne. The change fields used in SCENGEN are calculated as the difference in climate between the 15-year means of the control (1xCO2) and perturbed (2xCO2) simulations. The climate sensitivity of the experiment was 2.2deg C and the global precipitation sensitivity was 1.4% per deg Celsius of warming.

Mean monthly precipitation pattern correlation coefficient = 0.61
