| When was the current long-range forecast system implemented? |
October 2022 (DJF2022 in WMOLC-LRFMME) |
|---|---|
| Is it a coupled forecast system? | No |
| Is it a Tier-2 forecast system? | Yes |
| Atmospheric model resolution | 0.9x0.72 degree lon-lat, 96 vertical levels |
| Ocean model (if applicable) | N/A |
| Source of atmospheric initial conditions | Operational HMCR 3D-Var analysis for upper-air fields; OI analysis for screen-level temperature and humidity; simplified extended Kalman filter for soil moisture |
| Source of ocean initial conditions | N/A |
| If Tier-2, what is the source of SST predictions? | persistent SST and sea-ice anomalies |
| Hindcast Period | 1991-2015 |
| Ensemble size for the hindcasts | 11 members for each year (total number of hindcasts 275) |
| How is the hindcast ensemble configured | breeding; SPP in the model is partially activated |
| Ensemble size for the forecast | 41 |
| How is the forecast ensemble configured? | breeding (the same procedure as for hindcast ensemble, only the number of members differs); SPP in the model is partially activated |
| Length of forecasts | 135 days |
| Data format | GRIB 2 |
| What is the latest date predicted anomalies for the next month/season become available |
30th of the month prior to current. (E.g.) forecast for JJA is available on 30th April |
| How are the forecast anomalies constructed? | anomaly=forecast-(hindcast climate) |
