CLEX researchers found the ocean around Antarctica will warm under future emission scenarios, with the level of warming under the high emission scenario almost double that under the medium-low emission scenario.
By grouping weather systems by similar patterns rather than averaging conditions over months, seasons or years, CLEX researchers found that between Australia and Antarctica, the ‘doughnut’ structure of SAM is split into multiple ‘flavours’ and is more likely to have ‘bite marks’ out of it than be a perfect ring.
Despite the pandemic, the recent few months have seen a range of triumphs with completed PhDs being prominent among them. Our research has revealed the powerful influence of small scale and large scale ocean processes on our current and future climate.
Research has established a link between Antarctic stratospheric winds and an increased risk of weather conducive to bushfires from late spring to early summer. Further research on the relationship between winds and ozone in the Antarctic stratosphere could improve seasonal forecasts for Australia.
Research by CLEX scientists and colleagues re-examines some of the basic assumptions and interpretations in the theory. In particular, they show the SAM cannot be interpreted as a descriptor of mid-latitude variability and it has little imprint on the weather of the storm track.

A new study with Centre of Excellence researchers warns that changes in springtime winds high above the South Pole could trigger higher than usual heat waves and fire-prone weather conditions in Australia.
Observations from Antarctic seals fitted with scientific instruments have revealed how eddy driven transport may be driving the melting of ice shelves, with consequent impacts on sea-level rise.
The Climate Variability program has seen an extraordinary amount of activity over the past four months with new arrivals, a clutch of thesis submissions, awards, research voyages and a wealth of research.
In this project, you will use unique data collected during the Antarctic winter to understand the interactions between PSCs, the tropopause, and very cold cirrus clouds which are present in the upper troposphere. You will also determine how small-scale changes in stratospheric winds influence the occurrence, composition and brightness of PSCs.
