Hurricane Dynamics

Over the years our research group has published numerous papers on many aspects of hurricane dynamics, most notably including hurricane formation, early development, rapid intensification, spiral bands, secondary eyewall formation, and inner-core asymmetries, and radiation of spiral gravity waves.
