Dramatic decreases in Antarctic ozone (the so called ozone hole) have occurred since the late 1970s. While the initial focus on the ozone hole has been on the increased UV radiation reaching the surface, more recently it has been clear that the ozone hole may have an impact on other aspects of the atmosphere-ocean climate system. I will discuss recent observed changes in southern hemisphere tropospheric and ocean circulations, and the connection to the ozone hole. I will also examine simulated future changes, when ozone is expected to recover.

 

Brief Biography: Darryn Waugh is a Professor in the Department of Earth and Planetary Sciences at the Johns Hopkins University and the Department of Applied Mathematics, School of Mathematics and Statistics, UNSW.  His primarily research interests are large-scale atmosphere and oceanic flow and transport, with a focus on understanding global environmental issues such as stratospheric ozone depletion and climate change. In recent years his interests have expanded to include planetary atmospheres  and air quality. 
 
Darryn Waugh was born in New Zealand, and obtained Bachelor and Masters degrees in Mathematics from the University of Waikato, NZ in 1985 and 1987, respectively.  He earned his Ph.D. in Applied Mathematics at Cambridge University, UK in 1991. He was a post-doctoral fellow at MIT and a research scientist at Monash University, Australia, before joining the Hopkins faculty in 1998.
