This figure shows the anomaly correlations for forecasts with CAM and with reanalyses models. It illustrates that the CAM forecasts of the large scales are comparable to those from the operational NWP models used to produce the reanalysis. The green and yellow curves are from CAM2 starting from ERA40 and NCEP R2 reanalyses respectively. The blue and red curves are form the ECMWF and NCEP models used to produce the ERA40 and NCEP R2 reanalyses respectively.
