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.
