1 The National Earth System Prediction Capability ESPC 1 The National Earth System Prediction Capability (National ESPC) Project Daniel P. Eleuterio, Office of Naval Research Jessie Carman, NOAA Office of Ocean and Atmosphere Research Fred Toepfer, NOAA National Weather Service Dave McCarren, Naval Meteorology and Oceanography Command US THORPEX Legacy Planning Meeting June 5, 2014

2 The National Earth System Prediction Capability ESPC 2 National ESPC Overview An interagency collaboration, initiated between Navy, Air Force and NOAA and expanded to DoE, NASA, and NSF in 2012, for coordination of research to operations of a National earth system analysis and prediction capability. The original project combined global weather models in an operational synoptic multi-model ensemble under NUOPC. Seeks improved communication and synergy, for global prediction of weather, ocean, and sea ice conditions at weather to short-term climate variability timescales. Common prediction requirements and forecast model standards that enable agencies to improve leverage and collaboration. A national research agenda that will improve prediction across scales from days to decades. Cooperative focus projects to assess predictability of global scale high impact environmental conditions to inform S&T, R&D, and transition to operations. Towards an multi-model ensemble based air-sea-land coupled global prediction capability

4 The National Earth System Prediction Capability ESPC 4 Defense Department Challenges – A Global Force for Good 4 We provide worldwide forecasts to support DoD Operations – from the tropics to the poles, and from the depths of the ocean to the edges of space, across the coast to support stability operations, humanitarian assistance and disaster relief. Home Field Advantage … at the Away Games

5 The National Earth System Prediction Capability ESPC 5 From Sources of Predictability at Weather to Seasonal/ Climate Variability Timescales to Operational Prediction through Global Coupled Model Ensembles

6 The National Earth System Prediction Capability ESPC 6 NRC Study on Subseasonal to Seasonal Forecasting This study will identify: Potential sources of predictability and assess their relative value for advancing predictive skill; Process studies for incorporating new sources of predictability into forecast models; Opportunities for application and advancement of atmosphere-ocean-land-sea ice coupled models at S2S timescales (a few days to several weeks); Key observations needed for model initialization and verification of S2S forecasts; Techniques for uncertainty quantification and verification of probabilistic products; and Infrastructure requirements for computational, data storage and communication, and visualization techniques needed to make high resolution data assimilating global coupled ensembles an operational reality.

13 The National Earth System Prediction Capability ESPC 13 The call for Extended Range Products in the S2S Gap (Federal/Operational, Credible, Reliable, Calibrated, and Probabilistic) When initialized anywhere in phase space, the solution collapses toward this attractor. However, behavior of the trajectory is extremely sensitive to the initial conditions. -- Ed Lorenz (1963) Every day meteorologists predict next week’s weather…..Research is underway to develop models that will help them make predictions on an even longer timescale, seasonal forecasts of monsoon rains for example. --Tim Palmer, A weather eye on unpredictability (1991) Nearly 25 years later are we as far along as we should be?
