A coordinated Intraseasonal Oscillation (ISO) hindcast experiment, which is supported by APCC, CLIVAR/AAMP, and the AMY (2007-2011), was launched, in January 2009. This project aims to estimate intraseasonal predictability and determine realized prediction skill in the state-of-the-art climate models, including major operational centers’ models worldwide. The ISO hindcast experiment includes a set of retrospective ISO forecasts that covers the last 20 years from 1989 to 2008.
