Research brief: Hemispheric index fails to capture Variations in winds around Antarctica

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.

Briefing note 11: Research on the Antarctic stratospheric polar vortex is important for Australia’s seasonal forecasts

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 brief: SAM may be unrelated to mid-latitude weather.

February 12, 2020 1:38 pm Published by Comments Off on Research brief: SAM may be unrelated to mid-latitude weather.

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.

UTas01: Understanding polar stratospheric cloud interactions

July 20, 2019 1:00 am Published by Comments Off on UTas01: Understanding polar stratospheric cloud interactions

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.
