2. Bottom Line Up Front Question: What are Navy strengths in Tropical Cyclone Research? - Development of Navy models NOGAPS / COAMPS - Funding of academia, industry and federal laboratories - Vigorous research program in coupled ocean and atmosphere models - Efficient end-to-end research to operations transition Question: Which research priorities detailed in the inter-agency strategic research plan is Navy addressing? - Coupled ocean-atmosphere modeling and data assimilation - Quantitative use of remote sensing observations - Impact of Tropical Cyclones on the maritime domain Question: What resources can Navy bring to bear on TC research? - Basic research (6.1) ~ $3.5M / yr - Applied research (6.2) ~ $2M / yr - Transition to Operations (6.4) ~ $600K / yr

3. BLUF (Cont) Question: From the policy perspective, how can Navy help gain inter-agency support for TC research through individual agency budgets and on Capitol Hill? Navy will continue to participate at the appropriate mission level in Joint development programs and interagency activities

4. 59 th IHC -Operational Requirements 2005 Validated 14 Operational Requirements of the TC Forecast and Warning Centers Department of Defense emphasized their top three Operational Requirements (OR): 1. Improved track forecasts out to 5 days 2. Improved structure forecasts: radius of 50-kt and 35-kt wind radii 3. More accurate forecasts of wave heights and radius of 12 foot seas

5. 60th IHC - Research Requirements 2006 Automated Tropical Cyclone Forecast (ATCF) ) system developed by Naval Research Laboratory (NRL), Monterey to optimize the forecasting process. Operational Users include: Joint Typhoon Warning Center National Hurricane Center Central Pacific Hurricane Center Navy sponsored R&D includes: Tropical Cyclone Genesis Probabilistic Prediction of High Impact Weather Multi-Scale Tropical Dynamics Developmental efforts in Ocean Coupling and Data Assimilation directly enable TC track and intensity forecasts

6. A new ONR Department Research Initiative (DRI) beginning in FY08 -First major WESTPAC field experiment since TCM93 - $10M over 5 years (basic research), leveraging T-PARC -Focus on lack of understanding of storm scale processes (the biggest knowledge gap) GOALS: - Increase the predictability of the environmental forcing, formation, outer wind structure and intensity of TCs over the western North Pacific - Reduce errors in TC structure and intensity forecasts by 50% within a decade The Impact of Storm-Scale Processes on the Predictability of Western Pacific Typhoons POCs: Ronald J.

8. ONR - Science Issues/Gaps: Forecast models do not represent all the physics Up-scale transfer of energy is not well understood. Observations are sparse/inadequate in critical regions Inadequate quantitative use of all the available RS data Storm scale processes are poorly understood Progress is now possible on TC Evolution Problem Models & DA are getting better Coupling to the ocean, modulated by waves Cloud-resolving model skill has advanced Experimental assets will be available in the WestPac for the first time since 1993 Once-a-decade opportunity T-PARC has focused the research community Many new satellite remote sensing tools have become available since ’93 Several more by 2008 Verification vs. TC observations has never been done 9-km

9. ONR - Naval Relevance Increased medium-range predictability of the tropical large-scale environmental factors that influence tropical cyclone formation Increased predictability of the location, timing, and rate of tropical cyclone formation over the western North Pacific Increased predictability of the evolution of the outer-wind structure of intensifying and mature tropical cyclones over the western North Pacific Increased understanding and predictability of factors that determine motion of a TC through ET or landfall over the western North Pacific
