Item Open Access Airborne radar observations of rainband structure in Hurricane Ophelia (2005)(Colorado State University. Libraries, 2017) Razin, Naufal, author; Bell, Michael M., authorOne of the mechanisms proposed for the spin-up of the tropical cyclone (TC) mean tangential (swirling) circulation is the convergence of absolute angular momentum above the boundary layer in the outer-core region, which results in the broadening of the TC wind field. Mid-level inflow associated with TC rainband stratiform precipitation may be instrumental in spinning up the broader circulation and may be important in the development of secondary eyewalls. This analysis shows the concurrent presence of an elevated tangential wind maximum and a distinct mid-level inflow in the stratiform region, consistent with the proposed mechanism for TC intensity change.Item Open Access Diagnosing the rapid intensification of Hurricane Patricia (2015) from observations(Colorado State University. Libraries, 2017) Martinez, Jonathan, author; Bell, Michael M., authorHurricane Patricia (2015) made history as the strongest tropical cyclone in the western hemisphere with a peak intensity of 185 knots. Patricia set various records with the most noteworthy being its unprecedented rapid intensification of 105 knots in 24 hours. Although this dramatic intensification was not well captured by forecast models, high-resolution observations gathered by aircraft penetrating the eye of Patricia allow for a thorough investigation of the mechanisms that may have contributed to its evolution. Preliminary results suggest that Patricia’s ability to efficiently concentrate convection in a remarkably narrow annulus surrounding the eye led to its rapid intensification.
