2019 Hurricane Field Program Plan now available

One of the key aspects of NOAA’s Mission is, “To understand and predict changes in the climate, weather, oceans, and coasts...” with a long-term goal of achieving a, “Weather-ready Nation,” in which society is able to prepare for, and respond to, weather-related events. This objective specifies the need to improve the understanding and prediction of …

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 …

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 …

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 …
