CL Climate: Past, Present & Future

The 2016 Outstanding Student Poster and PICO (OSPP) Award is awarded to Christine McKenna for the poster/PICO entitled:

The influence of regional Arctic sea-ice decline on stratospheric and tropospheric circulation (McKenna, C.; Bracegirdle, T.; Shuckburgh, E.; Haynes, P.)

Christine McKenna is a PhD student at the British Antarctic Survey and Department of Applied Mathematics and Theoretical Physics, University of Cambridge. Her research uses climate modelling to investigate the dynamical mechanisms that may link Arctic sea-ice loss with changes in mid-latitude weather and climate. The EGU 2016 poster presented the results of some initial modelling experiments, which confirm that the mid-latitude winter response to Arctic sea-ice loss is highly sensitive to the region of sea-ice loss. However, key contrasts between the early and late winter response are also identified. Stratosphere-troposphere coupling may play a role in these differences.
