Towards a climate theory of tropical cyclone formation. In Earth's current climate, about 80 to 90 tropical cyclones form every year around the globe, but the reasons why cyclones form at this rate are unknown. This project will use a combination of theoretical techniques and numerical simulation to elucidate the links between large-scale climate and the rate of tropical cyclone formation. A series of climate model experiments will be performed that also have the potential to improve confidence ....Towards a climate theory of tropical cyclone formation.

Coupling tropical cyclone and climate physics with ocean waves. It is argued that without accounting for the wave effects directly, the physics of large-scale air-sea interactions is inaccurate and incomplete. The project will introduce explicit coupling of large-scale atmospheric and oceanic phenomena with the physics of surface waves which should lead to improved predictions of tropical cyclones and climate.

Through a fusion of innovative analyses of observations and fundamental science advances, alongside the development of ultra-high resolution climate models, the Centre looks to address climate science’s grand challenge in anticipating the likely weather patterns of a warmer world. The Centre strives to transform climate research by focussing on what matters most to making critical adaptation and mitigation decisions – weather change. The Centre aspires to provide Australia with the knowledge, technology, and human capital for robust evidence-based decision-making in response to future weather changes in our region and to harness weather as a resource.Read moreRead less
The weather-climate connection in Australian climate change. This project aims to uncover the key links in Australia's weather-climate connection by identifying the role weather features play in influencing the slowly varying climate and how changes in one might affect changes in the other. Better describing the two-way connection between weather and climate through an innovative combination of research techniques usually applied to only one of weather or climate will allow for a more insightful ....The weather-climate connection in Australian climate change. This project aims to uncover the key links in Australia's weather-climate connection by identifying the role weather features play in influencing the slowly varying climate and how changes in one might affect changes in the other. Better describing the two-way connection between weather and climate through an innovative combination of research techniques usually applied to only one of weather or climate will allow for a more insightful assessment of climate model quality. This assessment will support the identification of the most reliable climate models and, by using them, reduce uncertainties in future predictions. Improved predictions of climate in turn will enable better decision making in all sectors of society.Read moreRead less
Cloudiness over the Southern Ocean: reducing a key knowledge gap and source of climate model uncertainty. Southern Ocean clouds are key ingredients of the global climate system and yet are only poorly understood and poorly represented in climate models. Through the use of advanced observational analysis techniques this research will provide a deep understanding of key Southern Ocean cloud regimes and improve their representation in models.

Extratropical Cyclones and their Associated Precipitation: Understanding, Model Evaluation, and Future Projections. Storms and their associated frontal systems are responsible for producing most of the precipitation in mid-latitudes. This project will combine several powerful analysis techniques to answer some fundamental and currently unanswered questions on storm-related precipitation, including the extremes.

Storms and their associated frontal systems are responsible for producing most of the precipitation in mid-latitudes. This project will combine several powerful analysis techniques to answer some fundamental and currently unanswered questions on storm-related precipitation, including the extremes. State-of-the-art climate models, our main tool in projecting future climate changes, will then be evaluated to ensure they are able to capture the essential processes of storm-related precipitation that have been elucidated. This is essential to increase confidence in the projection of storm changes and their related precipitation, thereby providing better information to water managers.Read moreRead less
Weekly cycles of atmospheric parameters over Australia and the quantification of human influences on climate. Many human activities are organised on a seven-day cycle. The consequences of this might be expected to appear in the average variations of meteorological parameters across the week. This research will investigate these intra-week variations at many locations across Australia and will provide a critical insight into the human impact on climate.

Improving the seasonal prediction of Australian rainfall extremes. This project aims to investigate the predictability of Australian extreme rainfall using the latest Bureau of Meteorology seasonal prediction system and new re-analyses and climate models. Extreme rainfall events in Australia are often associated with loss of life and damage to infrastructure and the environment, but some impacts can be mitigated with improved forecasting. This project will analyse influences of climate change an ....Improving the seasonal prediction of Australian rainfall extremes. This project aims to investigate the predictability of Australian extreme rainfall using the latest Bureau of Meteorology seasonal prediction system and new re-analyses and climate models. Extreme rainfall events in Australia are often associated with loss of life and damage to infrastructure and the environment, but some impacts can be mitigated with improved forecasting. This project will analyse influences of climate change and climate variability on seasonal-scale predictability of extreme rainfall. This will increase our understanding of the processes behind extreme rainfall events and where predictability arises from, and this would result in improvements in forecasting.Read moreRead less
Evaluating the weather in climate models - the relationship of dynamics and rainfall over Australia in current and future climates. Climate change will be experienced by society as a change in the day-to-day weather. This project will investigate the capabilities of modern climate models in simulating the weather with a particular focus on rainfall, and will provide guidance to the use of these models in projections of the future of Australia's climate.
Improving understanding of climate change and its impacts in Australia through detection and attribution of climate change.

This research will quantify the contribution to Australian regional climate change due to greenhouse gases, which will assist policymakers in reaching decisions about policies on emission reductions or adaptation to greenhouse climate change. Improved estimates of uncertainties in future regional climate changes due to increasing greenhouse gases will allow better quantification of their likely impacts, estimation of the costs or maximising any benefits from regional climate changes. Through collaboration with the Bureau of Meteorology and CSIRO, this research enhances Australia's capabilities in diagnostic analysis of climate variability and change, and aids the development and evaluation of new Australian climate models.
