System Configuration Information
These information can be changed if the corresponding operational model is modified.
GPC Montreal
| When was the current long-range forecast system implemented? | Implemented on June 11, 2024 (the first official forecast is issued on July 1st, 2024) |
|---|---|
| Is it a coupled forecast system? | Yes |
| Is it a Tier-2 forecast system? | No |
| Atmospheric model resolution |
T63L35, 1.1ºx1.1ºL85 |
| Ocean model (if applicable) |
CanNEMO3.4: - 1 x 1 deg/ORCA1 (L45) NEMO3.6: - 1 x 1 deg/ORCA1 (L50) |
| Source of atmospheric initial conditions | CMC Global analysis is assimilated |
| Source of ocean initial conditions | CMC SST and sea-ice analysis at the surface and CMC GIOPS 3D ocean analysis below the surface. |
| If Tier-2, what is the source of SST predictions? | N/A |
| Hindcast period | 1991-2020 |
| Ensemble size for the hindcasts | 40 members: 20 members from GEM5.2-NEMO + 20 members from CanESM5 |
| How is the hindcast ensemble configured? | Hindcast is made with each individual model with 20 members of 12-month integration initialized at the beginning of each month (ensemble members 1-10) and five days beforehand (ensemble members 11-20). |
| Ensemble size for the forecast | 40 members, 20 for each model |
| How is the forecast ensemble configured? | Forecast is made with each individual model with 20 members of 12-month integration initialized on the last day of the previous month (ensemble members 1-10) and four days beforehand (ensemble members 11-20). |
| Length of forecasts | 12 months |
| Data format |
GRIB2 |
| What is the latest date predicted anomalies for the next month/season become available? | The forecasts will be available every first day of the month. |
| How are the forecast anomalies constructed? | Since hindcast data are already provided (https://dd.weather.gc.ca/model_cansips/100km/hindcast/), one can produce the forecast anomalies by subtracting the ensemble forecast values from the hindcast mean |
