Data Seasonal Progs SST Gradients TC Research Roughly Aligned with Operational Priorities Intensity & Structure: ~ 35%

5. OFCM-Sponsored Working Group for Tropical Cyclone Research 5 WG/TCR Snapshot analysis of all agency research efforts mapped against research needs and operational priorities –Fairly even distribution of TC research investment among agencies cover most operational priorities –Intensity/structure change #1, but very difficult –Captures >90% research in 75 IHC abstracts –Work in progress Summary

6. OFCM-Sponsored Working Group for Tropical Cyclone Research 6 WG/TCR Areas of Concern / Gaps –Little emphasis on forecaster aids (guidance on guidance) Not just an applied research problem Needs greater emphasis in basic as well as applied Include math / probability community –Little emphasis on resolution vs. ensemble model output* Summary * First HFIP issue

7. OFCM-Sponsored Working Group for Tropical Cyclone Research 7 WG/TCR Areas of Concern / Gaps (continued) –Continue global model improvement (NUOPC) –Major Concern / Gap Lack of inclusion of social science and associated decision-making issues related to TC research Summary

8. OFCM-Sponsored Working Group for Tropical Cyclone Research 8 WG/TCR Next steps of WG/TCR –Develop set of interagency strategic objectives driven by requirements (intensity/structure, track, RI, genesis) –Relate research efforts toward achieving strategic objectives –Document continued work of WG/TCR –Formalize executive oversight –Address major concern to address social science and decision-making issues Summary
