Figure 13. NOAA/NCEP operational dynamical predictions of June-August seasonally averaged precipitation anomalies (% of climatology, left) and surface temperature anomalies (°C, right). Probability distribution functions as in Fig. 7. Spatial anomaly maps as in Fig. 6, except based on the ensemble mean of the CFS forecasts. For CFSv1, 435 (124) individual hindcasts (forecasts) are used for 1981-2009 (2011). For CFSv2, 696 (124) individual hindcasts (forecasts) are used for 1982-2010 (2011All hindcasts and forecasts are based on initializations from May analyses, and anomalies are calculated relative to the period of available hindcast climatologies for all May initializations.
