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
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
Drs. Sundararaman Gopalakrishnan (Gopal - left) and Robert Rogers (right) have both been selected for NOAA's Leadership Competencies Development Program (LDCP). The LCDP is an 18 - month program providing participants a series of cross-line, multidisciplinary training and learning experiences to broaden their understanding of NOAA’s strategic vision, mission, and goals, as well as business processes. The … Continue reading Gopal and Rob Rogers selected for the NOAA LCDP Program
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
