Topical collection of Climate Forecast System version 2 (CFSv2) papers

A topical collection of Climate Forecast System version 2 (CFSv2) papers was co-organized by NOAA's Climate Program Office and the National Centers for Environmental Prediction (NCEP).

CFSv2 is a couple global climate model used for operational intraseasonal-to-interannual prediction. NCEP developed CFSv2 over the course of several years and implemented into operations in March 2011. Climate Program Office sponsored research significantly contributed to the development of CFSv2. A CFSv2 Evaluation Workshop was held in 2012 to bring broader climate community together with NCEP scientists to evaluate CFSv2 for its utility for climate modeling research and as a climate forecast tool.

This topical collection includes a selection of peer-reviewed papers presented at the workshop. The 20 plus papers in this collection have documented progress in CFSv2 performance in simulating intraseasonal-to-interannual climate variability and prediction key climate variables compared to its previous version.

This collection of papers should provide insight for the development of the next generation CFS. The collection co-organized by NCEP and the Climate Program Office is now accessible at




Americans’ health, security and economic wellbeing are tied to climate and weather. Every day, we see communities grappling with environmental challenges due to unusual or extreme events related to climate and weather. In 2017, the United States experienced a record-tying 16 climate- and weather-related disasters where overall costs reached or exceeded $1 billion. Combined, these events claimed 362 lives, and had significant economic effects on the areas impacted, costing more than $306 billion. Businesses, policy leaders, resource managers and citizens are increasingly asking for information to help them address such challenges.
