Summary: Tropical cyclones (TCs) usually weaken when there is a large change in the wind speed or direction with height (wind shear) or when there is dry air in the core. Some TCs, like Hurricane Edouard (2014) can intensify, even rapidly, under these conditions. We use a series of model runs to understand how a … Continue reading Scientists show how Hurricane Edouard in 2014 rapidly intensified despite wind shear and dry air in paper published in The Journal of the Atmospheric Sciences
Trey presented a seminar titled “How do sheared tropical cyclones evolve towards symmetry before rapid intensification?" ABSTRACT: In seemingly similar environments, some moderately sheared tropical storms undergo rapid intensification (RI) evolving towards more symmetrical precipitation structures but others do not. What role do the vortex tilt, humidification, and precipitation symmetry play in helping distinguish those … Continue reading HRD Seminar – George “Trey” Alvey, CIMAS/HRD – 16 July 2019
