Current Status of Multi-Institutional
Retrospective Forecast Experiments

• The APCC/CliPAS team completed the four-season
  multi-institutional retrospective forecast
  experiments for the period 1979-2004 for
  advancing our understanding of climate
  predictability and determining the capability and
  limitations of the MME prediction. We collected 7
  two-tier and 7 one-tier predictions from 12
  institutions in Korea, USA, Japan, China, and
  Australia.
