1. Hurricane IreneAugust 28, 2011NOAA/NHC Damage: #7 with >$16 Billion.Track Accurate;Intensity Over-predicted.Hurricane SandyOctober 29, 2012NOAA/NHC Damage: #2 with >$68 Billion.Track Accurate;Surge Under-predicted.Avila & Cangialosi, 2012, Tropical Cyclone Report Georgas et al., 2014, J. of Extr. Even. Colle et al., 2015, J. Mar. Sci. & Engr.

2. Intensity is modulated by the warm or cold ocean.Initial coupling to ocean models was not helping.Steady Improvement

3. Tropical Cyclone Forecasting is a Global Issue for US Navy & NOAAHurricaneDamage measured in DollarsTyphoon & CycloneDamage measured in DeathsGreatest Seasonal Cycle:ChinaKoreaJapanGreatest Seasonal Cycle:Mid-Atlantic Northeast CanadaTropical Cyclone Tracks & IntensitiesSummer – Winter Sea Surface Temperature Difference

4. Mid AtlanticWinter (1-layer)Mid Atlantic Summer (2-layers)Cold PoolWhy unseen? Satellites cannot see below surface, Argo Floats do not extend into shallow waterSummer heating produces a highly stratified ocean - A warm surface layer + An unseen cold bottom layerMid- Atlantic’s Cold PoolYellow Sea’s Cold Bottom Water MassYellow SeaSummerYellow SeaSummerCold Bottom Water MassCold Bottom Water Mass

5. MARACOOS is Certified to Operate New Observing Technologies for US GovernmentCODAR HF Radar for Current MappingSlocum Underwater Glider for Sustained Subsurface Profiling ofTemperature, Salinity, Currents, …. Glider Communicating at SurfaceGlider Profiling Subsurface

6. Operations to Research (O2R) DemonstratedIntegratedOcean Observatoryidentifies processes responsible for rapid ahead-of-eye cooling.Atmosphericmodel sensitivities identify ahead-of-eye cooling as the missing process for rapid de-intensificationNOAA OAR
