CLEX researchers and colleagues quantified the air quality impact of the Black Summer bushfires of 2019/20 and COVID-19 in the south-eastern states of Victoria and New South Wales (NSW) using a meteorological normalisation approach.

Briefing note 11: Research on the Antarctic stratospheric polar vortex is important for Australia’s seasonal forecastsApril 7, 2020 2:51 pm Comments Off on 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.
The Montreal Protocol, an international agreement signed in 1987 to stop chlorofluorocarbons (CFCs) destroying the ozone layer, now appears to be the first international treaty to successfully slow the rate of global warming.
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.
