Australia has long been a land of extreme weather events but under climate change it is expected that at least some of these events could be more intense and may occur at profoundly different intervals than in the past. Extremes can include droughts and floods, or heatwaves, changes in the frequency of warm nights, increases in rainfall intensity etc.
This project will examine the key processes that effect long- and short-term weather and climate events, including determining the likely role that climate change plays as well as exploring how extremes may change in the future. As part of this research, the Centre will explore whether individual extreme weather events can be directly attributed to climate change. It will also explore the ways that year-to-year climate variations, such as El Niño, affect Australian weather extremes.
This research will reveal in more detail than ever before how extreme events are likely to change over Australia. It will dramatically improve the capacity of regional planners and policy makers to help vulnerable regions prepare for the future.
