  9. Recent Climate Prediction Advancements at NCEP • Climate Forecast System: first dynamic operational climate forecast model (implemented Aug 2004) • Climate Test Bed: established in 2005, focused on accelerating improvements in the Climate Forecast System and related seasonal forecast products Unprecedented increases in the skill of CPC official seasonal outlooks (20% or more; O’Lenic et al. 2007) due in part to CFS and to CTB milestones (e.g. consolidation tool)

  10. Accelerate improvements in the CFS and its use through accelerating Research-to-Operations (R2O) To accelerate R2O, need full support of Operations-to-Research (O2R) to enhance NCEP’s role in the transition process Be a partner within the international and national multi model ensemble enterprises Enhance the CPC operational product suite Address budget issues Ongoing Strategic Priorities

  11. Operations to Research (O2R) • Goal • To accelerate improvements in the NCEP Climate Forecast System by providing CFS to the broad research community • Deliverables • CFS, data, and support services to user community • Annual CFS User's Workshop • Mechanism • Model Test Facility (FY11-15 budget cycle) • Managed operational program between NCEP, CPO, and CTB • Technical and scientific support (help desk) • Reallocation of contract staff in FY09 is being considered • Benefits • Provides support for research with CFS outside NCEP (ARCs, NSF, etc) • Maximizes opportunities for community participation

  12. Operations to Research (O2R) Proposed Model Test Facility • NCEP will provide • Operational models (CFS, GFS) and data (e.g. reforecasts, reanalysis) • Helpdesk facilities, training for O2R staff, web services • Points of contact for collaboration • CPO will provide • Support for helpdesk, training, points of contact, web services • Grants Program (AOs) • CTB will provide • Transition Infrastructure for pulling in the Research (R2O) • Oversight and management • Links between Test beds (e.g. CTB and HTB, HMT) • Gaps • Resources for fully-staffed Model Test Facility • Resources for competitive transition activities, including pilot projects

  13. CTB Seminar Series • 2007-2008 • Topic: “CFS as a prediction system and research tool” • Alternating venue between NCEP and COLA • 2008-2009 • Expand to include the broader climate community • Alternating venue between NCEP, COLA, and ESSIC • Broader participation, to include NOAA Air Resources Lab (ARL) • Topic: 3 CTB Focus Areas • CFS Improvements • MME Prediction Systems • Climate Forecast Products • The seminar series will commence in October

  14. Developing a MME Prediction System • International MME in negotiations • National MME Strategy • Engaged CPO to request NOAA facilitation • Budget request for additional computing resources FY11-15 • Seeking to include concept in next CCSP Strategic Plan • Pursuing elevation through CLIVAR • NCEP has defined in-house strategy, requirements • Considering running GFDL model in house • Proposal for post doc at COLA for independent evaluation of GFDL model • NCAR CCSM evaluations currently underway via CTB @ COLA

  15. Developing a MME Prediction System • National MME Strategy • However • Need MOUs with partners for exchanges of operational models and real time forecast data • NCAR and NASA have their own time lines for model development • CTB resource limitations • Insufficient computer resources to run hindcasts for other organizations • Skill assessments • Post-processing, calibration, consolidation, and preparation for operations

  16. Budget Issues To improve climate predictions and enhance NOAA’s climate product suite, need full CPO support for the CFS, the CTB and its expanded vision, and related transition activities • O2R – Model Test Facility – people, data access, helpdesk, training • CFS next Reanalysis (1979-2007) • CFS next Retrospective Forecasts (1981-2007) • AO for selected topics, including enhanced understanding of climate phenomena to improve CFS • Visiting Scientist Program • MME strategies

  17. Summary • NCEP is eager and willing to improve NOAA’s climate prediction capability and product suite • CTB is included in the NCEP Annual Operating Plan with specific milestones linked to Science Steering Committee recommendations • CTB is developing stronger relationships with the climate community • CTB will build upon past successes and future strategies to move climate prediction forward through improvement of the CFS (FY10 implementation) and spin up of the MME approach to short term climate prediction

  19. R&D –vs – Transition ? • Transition costs have been, and still are, under- resourced • Within an era of constant or diminishing dollars, R&D and transition needs will likely be competing with each other. Now R&D Transition Future ? ? ? R&D R&D R&D Transition Transition Transition
