Multiscale Structure and Evolution of Earl (2010) during Rapid Intensification

This talk will present airborne Doppler observations of the inner-core structure and evolution of Hurricane Earl (2010) during its rapid intensification (RI) period. Earl was one of the most intensively-sampled lifecycles of rapid intensification on record, with NOAA P-3 flights occurring every 12 h for 60 h, encompassing the time period before, during, and at the end of Earl's RI. Symmetric and asymmetric kinematic fields will be shown, with an emphasis on their evolution during Earl's RI and how they relate to recent airborne Doppler composite-based work showing the inner-core structure of intensifying tropical cyclones. Additionally, the distribution of convective bursts within Earl will be examined. The relationship between the symmetric and asymmetric vortex flow and the radial and azimuthal distribution of convective bursts will be discussed.
