This pege provides diagnoses of CFSv2 overall performance based on its retrospective forecasts (or hindcasts) for initial months from January 1982 to December 2009. Forecasts are initiated from every 5th day starting from January 1 of each year. The forecasts from each initial day consists of 4 members of forecast runs and 9 target months. Verification shown in this page is based on the ensemble mean from 20 members in each initial month.
The plots include statistics for two-dimentional (xy) fields and indices of sea surface temperature (SST). The SST indices include: Nino34(170W-120W,5S-5N).
Statistics are calculated for seasonal mean for 0-6 month lead. The observed andCFSv2 forecasts monthly anomalies are relative to the climatology from entire 28 years (1982-2009) hindcasts without any adjustment.
