NOAA NMME: North American Multi-Model Ensemble Seasonal Forecasts

The North American Multi-Model Ensemble (NMME) is an experimental multi-model seasonal forecasting system consisting of coupled models from US and Canadian modeling centers. The system was developed following a recommendation in a US National Academies report to meet regional prediction needs. Its multi-model ensemble approach is designed to quantify prediction uncertainty and has proven to produce better average prediction quality than single-model ensembles.

Use Cases

• Quantify seasonal forecast uncertainty based on the multi-model ensemble approach described.
• Compare prediction quality between ensemble and single-model forecasts as referenced in the description.
• Develop tailored regional climate predictions for decision support, a stated goal of the NMME system.
• Research model formulation uncertainty using outputs from multiple coupled models.

Strengths

• Incorporates models from multiple authoritative centers including NOAA/NCEP, NOAA/GFDL, NCAR, NASA, and Canada's ECCC.
• The multi-model ensemble approach is described as effective for quantifying uncertainty and producing superior average forecasts.
• Development was informed by a formal US National Academies report recommendation.
