Tropical CyclonesOutstanding R&D Needs • Rapid Intensity Changing Storms • Shear Effects on Track and Intensity • Statistical “Guidance-on-Guidance” on Model Output • Improved Data Assimilation • Improved Model Physics (microphysics, air-sea fluxes…) • Model Physics Sensitivities • Ensemble Techniques • Adaptive Observations/Targeting • Predictability Limits

  12. Tropical CyclonesSummary • Vision • 48-hr Track Forecast Error of 85 nm • 48-hr Intensity Forecast Error 12 kt • R&D Needs • Rapid Intensity Changing Storms • Shear Effects on Track & Intensity • Statistical “Guidance-on-Guidance • Improved Data Assimilation • Improved Model Physics • Model Physics Sensitivities • Ensemble Techniques • Adaptive Observations • Predictability Limits • Implement Hurricane WRF • Data Assimilation • Deploy Advanced Ensemble Techniques • Expand Adaptive Strategies • New Satellite Remote Sensing Increasing Performance • Aircraft Instrumentation Upgrades • Expand Targeted Observations Joint Hurricane Testbed 2002 2007 2012 2020

  13. Tropical CyclonesSummary • Improved track and intensity performances depend mostly on advances in numerical prediction/data assimilation • Intensity error performance is virtually “flat” – awaits significantly improved storm core specification and numerical forecasting R & D
