|When was the current long-range forecast system implemented?||July 2021|
|Is it a coupled forecast system?||Yes|
|Is it a Tier-2 forecast system?||No|
|Atmospheric model resolution||T359L137|
|Ocean model (if applicable)||NEMO v3.6 , ORCA 1/4° grid, 75 model levels. Frequency of coupling is 3 hours|
|Source of atmospheric initial conditions||ECMWF operational analysis|
|Source of ocean initial conditions||Mercator-ocean analysis|
|If Tier-2, what is the source of SST predictions?||N/A|
|Ensemble size for the hindcasts||25 members|
|How is the hindcast ensemble configured?||
3 lagged initialization (12 runs, 12 runs, 1 run), each built with 1 atmospheric condition from ERA5 and 1 oceanic condition from Mercator analysis.
For the 2 first initialization dates, ensemble generation by stochastic dynamics technique (Batté and Déqué 2016).The last initialization date begins the 1st of initialization month.
|Ensemble size for the forecast||51 members|
|How is the forecast ensemble configured?||
Same method as for the hindcast.
3 lagged initialization (25 runs, 25 runs, 1 run).
|Length of forecasts||7 months|
|Data format||GRIB 2 or ascii for digital data
Gif for graphics
|What is the latest date predicted anomalies for the next month/season become available?||13th of each month|
|How are the forecast anomalies constructed?||Departures from the model climate estimated by the hindcast integrations|
