USAF Tropical Cyclone Support and Needs Col Mark Zettlemoyer AF/A3O-WX 2 March 2009
OverviewAir Force Weather • Tropical Cyclone Support … 10 Years Ago • Current Forecast Accuracy & Needs • Critical Partnerships • Air Force Support • Research and Ops … Need your continued support
USAF Tropical Cyclone Support10 Years Ago • Typhoon warning capability critical to warfighters in Pacific/IO • Must continue to work JOINTLY to improve forecast and warning accuracy • Will take research and operational focus using technology as the enabler • The continued challenge: work the 10-year plan to improve forecast and warning accuracy by a factor of 3 or more
USAF Tropical Cyclone SupportForecast Accuracy Progress thus far … 30 years of focused R&D and T2 WPAC Intensity Error WPAC Track Error Impressive! Improvement factor 2.0 – 2.5! We must work this.
JTWC Operational Priorities • Intensity guidance/rapid intensification • TC/environmental characterization • Genesis guidance • Structure guidance
How to get thereCritical Partnerships Operational partnerships USAF/Navy TPC, CPHC NOAA: NWS, NESDIS, OAR RSMCs JTWC
USAF Tropical Cyclone SupportStrengths for Research • AF Weather has near-real time access to interrogatable imagery • Could be formatted and disseminated for research projects • Hurricane Hunters – WC130J • AFRC environmental recon mission corrects/validates satellite interrogation techniques • Leverage UAS capabilities
USAF Tropical Cyclone SupportStrengths for Research • Continues to send officers through Naval post graduate programs to earn tropical-related masters degrees • Joint Typhoon Warning Center (JTWC) operationalizes research through its techniques development section • JTWC data available in digital formats • Easily leveraged for research
USAF Tropical Cyclone SupportCommunity Help Need research community support • Top priority is intensity/structure…need improved: • Specification of cyclone structure (wind strength and distribution) • Satellite-based intensity/structure estimates • Forecast techniques for cyclone intensity/structure changes over time • Climate change influence on cyclone tracks / intensities • Impacts on strategic / failing states (e.g., Africa, Indian Ocean)
Operations input into research decisions (OFCM WG/TCR) Communications and interoperability (e.g., ATCF) National and international collaboration Data exchange, modeling Space-based sensing incl scatterometry and MW imagers/sounders USAF Tropical Cyclone SupportCommunity Help

USAF Tropical Cyclone Support Questions?
USAF Tropical Cyclone SupportAFIT Thesis Topics • Quantify the amount of forecast error attributed to initial position error in the major models • Determine intensity using passive microwave radiance data • Determine if rapid fluctuations in typhoon intensity could have been influenced by ocean heat content and TC heat potential • Identify sources of large forecast track errors • Develop rules of thumb to improve rapid intensification forecasting 24 to 48 hours before it occurs • Identify factors that may enhance or inhibit tropical cyclone development in the western North Pacific • Develop a monsoon depression climatology • Develop a midget tropical cyclone climatology
