  1. NOAA’s response strategy to the Hurricane Intensity Research Working Group (HIRWG) and related recommendations Greg Mandt NOAA NWS Office of Science and Technology 01 Feb 07 11-Jan-07 DRAFT 1

  2. Outline • Purpose • Issue • Background & Discussion • Alternatives • Coordination and Views • Output • Recommendation

  3. Purpose • Inform the NEP about the HIWRG and NSB reports - • Solicit NEP feedback on proposed strategy to formulate a NOAA response to satisfy request for a final briefing at the Fall 07 SAB • e.g., Constraints on the response?

  4. Issue • NOAA SAB chartered the Hurricane Intensity Working Group (HIRWG) to recommend how can NOAA further improve and advance hurricane intensity forecasting • NOAA Research Council tasked W/OST with preparing a response to the recommendations in the HIRWG and related proposals

  5. Background & Discussion • HIWRG issued final reports Jun06- • Majority report – 29 recomendations • Minority report – 7 recommendations • NOAA offices submitted comments on the draft HIWRG reports but NOAA has no formal response yet • National Science Board (NSB) report Nov06 Hurricane Warning: The Critical Need for a National Hurricane Research Initiative – • NSF Ratification expected soon (10Feb07) • NSB briefed NOAA SAB • Proposes creation of multi-agency National Hurricane Research Initiative (NHRI) to implement general recommendations • Proposes an additional annual investment of ~$300M in hurricane science and research • Provides a keystone recommendation, three implementation recommendations, 16 prioritized investments in four categories and other guidance

  6. Proposed Response Strategy • Evaluate the recommendations in the various NOAA plans, identify gaps, and issue a NOAA plan considering th HIRWG, NSB and OFCM reports - • OST organized working team – • Team has representation from the various interested programs (LFW, EMP, STI) and LOs (NWS, NHC, NCEP, OAR, AOML/HRD, ESRL; NESDIS pending) • Team contains all but ocean concerns (NOS postponed participation) • Water and Weather Hurricane and Related Inundation (HI) cross-cutting theme plan is starting point - • addresses many (but not all) HIRWG recommendations • HI plan provides comprehensive programmatic alternatives addressing many of the HIRWG issues • developed in coordination with • LOs: OAR, NWS, NOS, NESDIS • CEO, EMP, W+W’s LFW, Hydrology, Tsunami and STI programs • Not all alternatives in HI plan were adopted in final POPs submitted to PA&E • PA&E evaluated alternatives • PDM coming shortly; Team will evaluate PPBES and other internal alternatives against known gaps and emerging organizational and intergovernmental thrusts • Assumes additional resources and redirection are an option • Followed by OFCM/JAG/Tropical Cyclone Research report (soon to be released) along with other plans and requirement documents

  7. High-Level HIRWG Majority Report Recommendations and W&W Response (pending PDM) • HWRF model enhancements (including data assimilation & ensembles) • Coupled ocean-atmosphere model with appropriate physics • Accelerate achievement of 1 km model resolution • Field studies to improve and evaluate models • Utilize radar for modeling • Evaluate observing strategies • Upper ocean observations  Improved operations-research collaboration on modeling  Joint Hurricane Testbed and Developmental Testbed Center  Improve usefulness of forecasts through multidisciplinary research, including social science  Develop and test reduced and statistical models with operational data  Data archival system to make data sets available to research community  Limit how Saffir-Simpson scale is used  Develop a more complete suite of information  = Fully or Partially Addressed in Program Plan  = Included in Above Core = Not Addressed

  8. Alternatives • Status Quo is a scattering of plans addressing hurricane intensity forecasting and research- • Pro: each office/planning activity can state its particular vision • Con: lack of coherence; resource conflict; less coordination • Risk: High failure probability • Fiscal ramifications: Potential duplication of effort • Proposed Alternative: Produce unified NOAA Response Action Plan- • Pro: coherent and unifying; far-reaching; high-visibility; end-to-end; consistent with PPBES framework; metrics; responsive to operational requirements; may reduce duplication • Con: compromises will be required • Risk: TBD • Fiscal ramifications: may require additional resources and potential capability modification; farther reaching than PPBES temporally

  9. Coordination & NEP/Council Views • Coordination with: • NWS, OAR • PPBES/W+W, STI, LFW, CEO (later) • NEP/Council Views TBD: • NEP • CFO Council (required for any recommendation that costs money) • Other Relevant Council(s)

  10. Output • Provide response strategy to HIRWG and NSB reports for briefing at the Fall07 SAB meeting • Potential Unified NOAA Hurricane Intensity Action Plan • Addresses and assesses HIWRG, NSB, and OFCM reports • Consolidates and guides relevant cross-NOAA activities

  11. Recommendation • Endorse the proposed strategy and team composition
