HRD Seminar – Prof. Rupert Klein, Freie Universität, Berlin, Germany – 8 March 2019

Prof. Klein presented a seminar titled “Multiscale asymptotics for strongly tilted tropical vortices”. ABSTRACT: The asymptotic theory for three-dimensional vortices in the gradient wind regime by Paeschke et al. (2012), JFM, vol. 701, 137--170 is revisited. The theory considers vortices that are nearly axisymmetric at each vertical level but involve relative horizontal displacements of the … Continue reading HRD Seminar – Prof. Rupert Klein, Freie Universität, Berlin, Germany – 8 March 2019

HRD Seminar – Dr. Chris Collimore, Joint Institute For Regional Earth System Science and Engineering, UCLA – 5 March 2019

Dr. Collimore presented a seminar titled “The Impact of High Aerosol Concentrations on Tropical Cyclone Formation". ABSTRACT: Prior studies have shown that high levels of aerosols in the environment of convective clouds can cause the convection to become more vigorous through a five step process. Tropical cyclones (TCs) start as clusters of convective clouds and … Continue reading HRD Seminar – Dr. Chris Collimore, Joint Institute For Regional Earth System Science and Engineering, UCLA – 5 March 2019

AOML & HRD Seminar – Dr. Bo-Wen Shen, San Diego State University – 25 February 2019

Prof. Shen presented a seminar titled "Butterfly Effects and Chaos: New Insights Revealed by a Generalized Lorenz Model". Abstract Is weather chaotic? A view that weather is chaotic was proposed and is recognized based on the pioneering work of Prof. Lorenz who first introduced the concept of deterministic chaos. Chaos is defined as the sensitive … Continue reading AOML & HRD Seminar – Dr. Bo-Wen Shen, San Diego State University – 25 February 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

HRD Monthly Science Meeting of December 2018

December’s science meeting consisted of seven presentations: Dave Raymond: "The Organization of Tropical East Pacific Convection (OTREC) Field Campaign" Xuejin Zhang: "Development of Hurricane Analysis and Forecasting System" Rob Rogers: "Summary of the 2018 HFP-IFEX" Dr. Chris Barnett: "Overview of JPSS Atlantic/SAL Field Campaign Activities" Gus Alaka: "Verification of the 2018 Basin-Scale HWRF" Michael Fischer: … Continue reading HRD Monthly Science Meeting of December 2018

HRD Seminar – Dr. Dave Raymond, New Mexico Institute of Mining and Technology – 12 December 2018

Prof. Raymond presented a seminar titled “Control of Convection in High-Resolution Simulations of Tropical Cyclogenesis”. ABSTRACT: Three idealized high-resolution simulations of tropical storm formation from a weak vortex are analyzed. The three simulations include a case using warm rain microphysics, a case in which surface friction is omitted, and a case in which ice microphysics … Continue reading HRD Seminar – Dr. Dave Raymond, New Mexico Institute of Mining and Technology – 12 December 2018
