Date: Monday, 30 July, 2018 – 18:00 to 19:30
Where: Tyree Room, John Niland Scientia Building, UNSW Sydney
Join Professor Darryn Waugh from Johns Hopkins University and UNSW for an enlightening discussion around the enduring impact of the ozone hole on climate.
The discovery of a dramatic decrease in the protective ozone layer high above Antarctica generated worldwide concern and ultimately led to the landmark 1987 Montreal Protocol banning ozone-depleting chemicals. While the initial focus on the ozone hole was increased UV radiation reaching the surface, more recently it has become clear that the ozone hole may have an impact on other aspects of the atmosphere-ocean climate system.
Darryn will discuss recent observed changes in southern hemisphere tropospheric and ocean circulations, and the connection to the ozone hole. He will also examine simulated future changes, and when ozone is expected to recover.
About the speaker: Professor Darryn Waugh is one of the world’s preeminent research scientists in atmospheric, ocean, and climate sciences. He is currently a Professor of Earth and Planetary Sciences at Johns Hopkins University (USA), and in 2017 joined the UNSW School of Mathematics and Statistics on a part-time basis.
Professor Waugh has been the lead investigator on several NASA projects, and is a co-investigator on multi-million dollar funded NSF Frontiers in Earth System Dynamics initiatives. His main research interests are oriented toward understanding dynamics and transport in the atmosphere and oceans.
He has attracted a collection of prestigious awards and fellowships throughout his career, including two NASA Group Achievement Awards, the Francois N. Frenkiel Award, and two AGU Editors Citations for Excellence in Refereeing. He completed his PhD in Applied Mathematics at Cambridge University in 1991.
