AOML/HRD Seminar – Evan Forde – 29 August 2019

Evan presented a seminar titled "Relationship between Tropical Cyclone Genesis in the Main Development Region and Seasonal Tropical Cyclone Activity in the Atlantic Basin".  ABSTRACT Tropical Cyclone (TC) genesis in the Atlantic basin main development region (MDR) was evaluated from 1972-2015 to determine its relationship with seasonal TC activity.  Among other findings, a strong correlation … Continue reading AOML/HRD Seminar – Evan Forde – 29 August 2019

HRD Seminar – Kelly Nuñez Ocasio, NERTO and Pennsylvania State University – 19 July 2019

Kelly presented a seminar titled “PV budget analysis on high resolution simulations to understand the interaction of AEWs with associated convection". Abstract: The role of convection and associated potential vorticity  (PV) generation have been shown to be significant in the evolution of African Easterly Waves (AEWs); however, how the evolving AEWs lead to tropical cyclogenesis … Continue reading HRD Seminar – Kelly Nuñez Ocasio, NERTO and Pennsylvania State University – 19 July 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
