The Climate Forecast System or coupled forecast system (CFS) is a medium to long range numerical weather prediction and a climate model run by the National Centers for Environmental Prediction (NCEP) to bridge weather and climate timescales. [1] Version 2 became operational as CFSv2 in 2011. [2]
Though the almanac claims an 80% accuracy rate on long-term weather forecasts, the organization also admits its 2023 predictions were significantly less accurate than this usual claimed rate.
