Summary • historic dataset collected in Hurricane Earl • nearly complete lifecycle, sampled at 12-h intervals for inner core by P-3’s, 24-h intervals for environment by G-IV • significant RI episode sampled by Doppler radar prior to, during, and after • steady-state period as a major hurricane sampled, including vortex interaction with increasing upper-level SW shear • weakening stages sampled, including period leading up to ET First thoughts on questions to address • how does vortex evolve during RI? Symmetric and asymmetric evolution? Kinematic and thermodynamic evolution? • what’s relative role of convective-, vortex-, and environmental-scale processes in RI? • how does mature hurricane respond to increasing vertical shear (tilt, wind field asymmetries)? • what is structural change during weakening and prior to ET? • and many more…..
