Meso- and Miso-scale structures in the eye and eyewall of major hurricanes
Understand and describe small-scale features in tropical cyclone eyewalls and their impact on intensity.
This will be accomplished by:
- analyzing dropwindsonde, flight-level, airborne Doppler radar, and other data within hurricane eyewalls
- Samples of dropwindsondes with extreme horizontal and vertical motions have been collected.
- High-resolution HEDAS analyses of Hurricane Fabian during the time of its polygonal eyewall structure (03 September 2003) have been completed.
- Complete study of extreme horizontal motions in eyewalls.
- Begin analysis of extreme vertical motions in eyewalls.
- Synthesize data during Fabian flight 02 September.
- Synthesize data during Felix flight 02 September.
- Analyze convective motions in the eye of Hurricane Emily (2005).
- Cluster analyses of all eyewall dropwindsonde data.
