Shown below are MJO forecast products using information from the operational GFS (i.e., single, higher-resolution run).
The Wheeler and Hendon (2004) methodology
is applied to the model forecast data and are equivalent to those perfomed on observations with necessary adjustments due to the use of realtime model forecast data. Please inquire for additional details if needed. The anomalies (with the seasonal cycle and interannual variability removed) are then projected onto EOFs based on observed data.
