    FURTHER EXPLORING THE POTENTIAL FOR ASSIMILATION OF UNMANNED AIRCRAFT OBSERVATIONS TO BENEFIT HURRICANE ANALYSES AND FORECASTS

    【摘要】:This study explores the potential of assimilating data from multiple instruments onboard high-altitude,longendurance unmanned aircraft to improve hurricane analyses and forecasts.A recent study found a signifi cant positive impact on analyses and forecasts of Hurricane Karl when an ensemble Kalman fi lter was used to assimilate data from the High-altitude Imaging Wind and Rain Airborne Profi ler(HIWRAP),a new Doppler radar onboard the NASA Global Hawk(GH)unmanned airborne system.The GH can also carry other useful instruments,including dropsondes and the Hurricane Imaging Radiometer(HIRAD),which is a new radiometer that estimates large swaths of wind speeds and rainfall at the ocean surface.The primary fi nding is that simultaneously assimilating data from HIWRAP and the other GH-compatible instruments results in further analysis and forecast improvement for Karl.The greatest improvement comes when HIWRAP,HIRAD,and dropsonde data are simultaneously assimilated.
