UKLO-EQ

This experiment was performed in the UK in 1986 using the UK Met. Office's low resolution 11-layer atmospheric GCM, coupled to a mixed-layer ocean. The horizontal resolution of the model is 5 deg. latitude by 7.5 deg. longitude. The results are from an equilibrium experiment reported in Wilson and Mitchell (1987). The experiment is referred to here as "UKLO-EQ" (although it is still widely referred to in the literature as "UKMO"). The results from this experiment were acquired directly from John Mitchell's group at the UK Met. Office during 1988 and 1989. 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 model has a climate sensitivity of 5.2degC and a global precipitation sensitivity of 3.0% per degree Celsius warming.

Mean monthly precipitation pattern correlation coefficient = 0.64
