50th Anniversary of Hurricane Camille

On the night of August 17-18th, 1969, Hurricane Camille came howling into Waveland, MS, with estimated sustained winds of 175 mph (280 km/hr) and a storm surge of 24 feet (7.3 m) to become the second strongest hurricane on record to make landfall in the United States (after the Labor Day Hurricane of 1935).  Camille also … Continue reading 50th Anniversary of Hurricane Camille

Paper on how tropical cyclones in shear intensify released online in Geophysical Review Letters

Summary: Tropical cyclones (TCs) are made up of thunderstorms (what we call convection), and these storms have strong winds moving up and down (what we call up- and downdrafts). Dry air enhances evaporative cooling (the same process that cools people when they sweat) from convective downdrafts, reducing the temperature and humidity in low levels; this … Continue reading Paper on how tropical cyclones in shear intensify released online in Geophysical Review Letters

HRD Seminar – George “Trey” Alvey, CIMAS/HRD – 16 July 2019

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
