Verifications of Global EPS for one-month prediction using its Hindcast
Hindcast Verification
- Bias map (Mean error map)
- Hindcast maps for every initial date
- Verification score
- Time-series Circulation Index
- Verification Score Maps
- Variables to be Assessed: RAIN, Z500, T850, SLP, CHI200, PSI200, PSI850
- Diagonostic Measures:
- Anomaly Correlation(ACOR)
- Root Mean Squared Error(RMSE)
Specifications of the hindcast
- Model: JMA-GSM
- Resolution: TQ479L128 (up to 18 days) , TQ319L128 (after 18 days)
- Target period for verification: 1991-2020
- Ensemble size: 13
- Initial condition (Atmosphere): JRA-3Q
- Initial condition (Land): Land surface values estimated with the land-surface model in the Global EPS using atmospheric forcing from JRA-3Q
Verification data
- Precipitation (RAIN) : GPCP (Global Precipitation Climatology Project) precipitation dataset (version 2.3)
- Atmospheric Analysis (such as Z500 and T850): JRA-3Q
- Sea surface temperature (SST) : MGDSST
