HRD Seminar – Dr. David Ryglicki, Naval Research Laboratory – 17 August 2017

Dr. Ryglicki presented a seminar titled  “The Kinematics of Rapidly Intensifying Hurricanes in Moderate Vertical Wind Shear”. Abstract: A select group of tropical cyclones (TCs) which unexpectedly undergo rapid intensification in moderate vertical wind shear are identified, analyzed, and modeled. Geostationary satellite and reanalysis data are used to identify features and environmental parameters of these TCs. …

Paper on how vertical wind shear impacts surface winds in hurricanes published in Monthly Weather Review

Summary: Scatterometers are instruments on aircraft or satellites that are used to measure wind speed and direction at the ocean surface. In this follow-up to a 2016 study, the surface wind in tropical cyclones around the world are studied using a large set of measurements from 2000 to 2011. The impact of tropical cyclone intensity, …
