Verification of One-month Prediction
- Error maps for every forecast (updated every week)
- Z500, T850 and SLP (Northern Hemisphere)
* Systemtic error is removed.(Bias based on hindcast from 1981 to 2010.)
- Stream Function, Velocity Potential, Precipitation,
Surface air temperature, Sea surface temperaturem, Z500 and SLP (Tropics)
* Model normals based on hindcast.
* Climatological normals:
- before 12 Mar. 2009: NCEP/NCAR reanalysis-1(1971-1978),ERA-15(1979-1993) and GANAL(1994-2000)
- 12 Mar. 2009 - 19 May 2011: JRA-25 (1979-2004)
- 19 May 2011 - 27 Feb. 2014: JRA-25/JCDAS (1981-2010)
- After 5 Mar. 2014 : JRA-55 (1981-2010)
- Historical score chart (52-weeks mean of scores)
- Z500 (NH; 20N-90N)
- CHI200, PSI200, PSI850 (Tropics; 20S-20N)
- Recent score chart
- Seasonal mean of scores
: Verification scores and charts are updated every month.
