HRD Seminar – Addison Alford, University of Oklahoma – 17 June 2019

Addison presented a seminar titled "Radar Observations of Landfalling Hurricanes: Synthesizing Three Years of SMART Radar Missions" ABSTRACT: The Shared Mobile Atmospheric Research and Teaching radars observed five landfalling tropical cyclones (TCs) from 2016-2018. The observations were largely targeted toward understanding asymmetric convective and dynamic processes. Such processes are thought to lead to the intensification … Continue reading HRD Seminar – Addison Alford, University of Oklahoma – 17 June 2019

Jason Dunion’s presentation at the most recent AMS Hurricane Conference highlighted in the December 2018 issue of the AMS Bulletin

At the recent American Meteorological Society Conference on Hurricanes and Tropical Meteorology, Jason presented his work with co-authors Chris Thorncroft, Chris Velden, and Brian McNoldy about the diurnal cycle of convection in hurricanes.  This cycle is a dramatic outward expansion of clouds that begins moving away from the storm center each day around sunset and … Continue reading Jason Dunion’s presentation at the most recent AMS Hurricane Conference highlighted in the December 2018 issue of the AMS Bulletin

30th Anniversary of Hurricane Gilbert

On September 16, 1988, Hurricane Gilbert made landfall at the Mexican city of La Pesca,Tamaulipas, with winds of 125 mph (200 km/hr).  It had already brought destruction upon the Yucatan peninsula and the Caribbean islands.  Along the way it set a new low-pressure record that would stand for 17 years. Gilbert was a classic Cape … Continue reading 30th Anniversary of Hurricane Gilbert

Paper on the direct measurement of important air-sea interaction parameters in tropical cyclones published in the Journal of Geophysical Research

Summary:Friction is what happens when two things rub up against each other; when this happens, they release heat. When this happens in the atmosphere, we call it “dissipative heating.” Tropical cyclones (TCs) mainly gather energy from the warm ocean at the boundary layer, the region from the surface of the ocean to an altitude of … Continue reading Paper on the direct measurement of important air-sea interaction parameters in tropical cyclones published in the Journal of Geophysical Research
