1 US THORPEX Legacy Planning Meeting
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 - What can be done to facilitate the US research and operational communities to more effectively engage in the three THORPEX-Legacy projects? - How to foster international collaborations for mutual benefit? - What are some key scientific issues that can quickly benefit from a more focused research effort? - How to further promote collaborations between the forecast science and the SERA research communities? - How to further promote research to operational transitions? Participants are encouraged to suggest additional themes to be considered for discussions.

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 Defense Department Challenges – A Global Force for Good
Home Field Advantage … at the Away Games 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.

5 From Sources of Predictability at Weather to Seasonal/ Climate Variability Timescales to Operational Prediction through Global Coupled Model Ensembles

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.

7 National ESPC Need: Seamless Full Earth System
(or at least “lightly seamed”) Partnerships: ESPC NOPP HFIP NMME USGCRP USCLIVAR NUOPC WWRP/WCRP National ESPC

8 Coupled Model Development Navy ESPC Highlights - Infrastructure
Design infrastructure for operational implementation for coupled system Define implementation across operational systems, architecture requirements, cycling setup including DA Note the single sided “one-way” arrows for the uncoupled system. The coupled system, on the right, contains the feedback between the main HYCOM and NAVGEM forecasting systems which have two subsystems in common, CICE and WW3. NAVGEM contains two unique subsystems its LSM and NAAPS which have indirect feedback with HYCOM primarily through NAVGEM flux output. “Operational Implementation Design” has details on data volumes, resources required, and operational job distributions “In press” as Naval Research Laboratory Memorandum Report search under author Metzger

10 Air Force Post-Processed Ensemble Products
Unlike Navy and NOAA, USAF does not develop their own global model nor share their forecast fields due to their licensing agreement. Instead they provide joint NUOPC Ensemble processing. Probability of Surface wind > 25, 35, 50 kts Lower and upper level moderate and severe turbulence Icing at 500, 700, 850, 925 mb Surface viz < 1, 3, 5 nm Surface temp < 32, > 90 Many Precip products and others All provided to NCEP NOMADS servers as operational fields, 6 hrs time steps out to 10 day leads for all fields. Plans for longer lead times and higher resolution in 2014/15. Probability of Surface Level Reduced Visibility Probability of Severe Fighter Index of Thermal Stress (FITS)

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?
