UKHI-EQ

This experiment was performed in the UK in 1989 using the UK Met. Office's high resolution 11-layer atmospheric GCM, coupled to a mixed-layer ocean. The horizontal resolution of the model is 2.5 deg. latitude by 3.75 deg. longitude. It is an equilibrium experiment reported in Mitchell et al. (1990) and Senior and Mitchell (1993) and is widely referred to as "UKHI-EQ". We acquired the results from this experiment in 1993 through the Climate Impacts LINK Project, based in the Climatic Research Unit. 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 climate sensitivity of the experiment was 3.4deg C and the global precipitation sensitivity was 2.7% per degree Celsius warming.

Mean monthly precipitation pattern correlation coefficient = 0.72
