The CLIVAR Working Group on Seasonal to Interannual Predicability is coordinating the WCRP Climate-system Historical Forecast Project. This is a multi-model and multi-institutional experimental framework for sub-seasonal to decadal complete physical climate system prediction. The ‘complete physical climate system’ implies contributions from the atmosphere, oceans, land surface cryosphere and atmospheric composition in producing regional and sub-seasonal to decadal climate anomalies. As part of the CFHP, I would like to bring to your attention the Sea-Ice Historical Forecast Project – a coordinated set of multi-model sensitivity experiments that have been proposed to examine the effects of sea ice initialization in seasonal prediction systems.
