Recent verification information for the ensemble mean and operational GFS MJO index forecasts. Historical verification is also provided using the available data record.

Phase diagram illustrating the recent verification of both the ensemble mean and operational GFS MJO index forecasts. The thick lines are the model forecasts and the thin line is the corresponding observations during the period. Only the forecast points for the first seven days are shown.

Anomaly correlation for RMM1 and RMM2 during the last 90 days for both the operational and ensemble mean GFS for leads from 1 to 15 days. The thick lines are the values for the ensemble mean GFS (GEFS) and the thinner lines are for the operational GFS (GFSOP).

Historical verification of the ensemble mean GFS via anomaly correlation for leads from 1 to 15 days for both RMM1 and RMM2. The validation period shown here is from January 2007-present.
