Large changes in the Southern Hemisphere circulation over the last sixty years have impacted on the properties of weather systems associated with mid-latitude storms and consequently led to reductions in rainfall, particularly over southern Australia.

Whether these trends are likely to continue into the future under increasing anthropogenic Greenhouse Gas forcing is an important question with direct consequences for rainfall over southern Australia.

This information is vital for enhancing our capability to identify and respond to emerging issues including Agriculture and water sectors such as implications for water resource management, food security, crop losses, and floodplain planning and management

Disaster risk management planners as well as those working in the impacts and adaptation space need to be well informed of the full range of possible future scenarios in order to effectively manage risks for their respective communities. Here we present results from a carefully selected set of the seven “best” models and examine how the observed 20th century trends in storm formation continue in a stabilisation mitigation scenario compared with a high emission world.
