Paper on how downdrafts in hurricanes affect intensity published in Monthly Weather Review

Summary: This study looks at differences between tropical cyclones that strengthen and those that do not using data collected by dropsondes, small instruments released from hurricane hunter aircraft that measure wind, temperature, and moisture as they fall to the surface. Important Conclusions: 1. The fuel that supports tropical cyclones is the heat and moisture from … Continue reading Paper on how downdrafts in hurricanes affect intensity published in Monthly Weather Review

HRD observation team monthly meeting – 15 August 2019

The purpose of the observation team meetings is to bring together the people who use observations in their research on a regular basis to discuss issues they’re having, provide updates on observations they’re analyzing or collecting, and any other information that may be of interest to the broader group.  These meetings are also an excellent … Continue reading HRD observation team monthly meeting – 15 August 2019

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

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
