Abstract:
As known from analysis of CMIP-2 runs, there is significant correlation between some systematic errors in reproducing of modern climate by given model, and model sensitivity to CO2 doubling. In particular, models that overestimate surface short wave radiation in regions with maritime stratocumulus, often have sensitivity to CO2 doubling higher than multi-model average, and vice versa. In this study, we plan to check this using AR4 data. Also, other possible correlations between systematic errors in reproducing of modern climate, and model climate sensitivity will be studied.
