The real-time monthly
forecasting system is combined VAriable Resolution Ensemble
Prediction System (VarEPS) and monthly forecasting system. On
Thursday of each week, the 00 UTC VarEPS forecast is extended from
15 to 32 days at a resolution of T319 L62 with ocean coupling
introduced from day 10. The raw hindcast monthly forecasting data
are a 4-member ensemble.
Parameters available
in dissemination for forecast range D+0 to D+15 are as described in
Ensemble Prediction System section. For forecast range D+15 to D+32
available parameters are listed in the tables bellow.
