–2000. Observational estimates are also shown in all figures from in situ measurements analyzed by Ganachaud and Wunsch (2003) and the reanalysis estimates from Trenberth and Caron (2001) (using the period February 1985 to April 1989) from both the NCEP–National Center for Atmospheric Research (NCAR) ( Kalnay et al. 1996 ) reanalysis and the 40-yr European Centre for Medium Range Weather Forecasts reanalysis (ERA-40), Uppala et al. 2005 ). Note the different scales for the vertical axes in each basin. In the

better than alternate configurations S1, S2, and S3, although scores often differ only very slightly. Table 3. 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
