Summary of root-mean-square error (rmse) and correlation (corr) between model configurations and various observations. Sea level pressure (SLP), and 200- and 850-hPa zonal wind (U200, U850) are compared to 40-yr European Centre for Medium-Range Weather Forecasts Re-Analyses (ERA-40s) ( Uppala et al. 2005 ); precipitation is compared to GPCP v2 ( Adler et al. 2003 ); shortwave and longwave

westerlies appears in the equatorial stratosphere around 10 hPa, and stratospheric westerlies at polar latitudes can be over 50% stronger than in the 40-yr European Centre for Medium-Range Weather Forecasts Re-Analysis (ERA-40). In the troposphere, westerly biases are smaller in CM3 than AM3 in the Southern Hemisphere but larger in the Northern Hemisphere. Fig . 14. Annual-mean, zonally averaged zonal wind (m s −1 ) for (a) AM3, (b) ERA-40, (c) AM3 minus ERA-40, and (d) CM3 minus ERA-40. Wind stresses in
