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.
The dynamics of subtropical anticyclones and the connection to drought, heatwaves and bushfires in southern Australia. The aim of the project is to understand the dynamics of anticyclones (high pressure systems) in the region of southern Australia. The study of anticyclones in the region is important because of their very strong connection to rainfall in the winter, and heatwaves and bushfires in the summer, and because so little work has been done on understanding what is the defining feature o ....The dynamics of subtropical anticyclones and the connection to drought, heatwaves and bushfires in southern Australia. The aim of the project is to understand the dynamics of anticyclones (high pressure systems) in the region of southern Australia. The study of anticyclones in the region is important because of their very strong connection to rainfall in the winter, and heatwaves and bushfires in the summer, and because so little work has been done on understanding what is the defining feature of the climate of southern Australia. Understanding what controls the location and strength of these features will go a long way to explaining how the climate of southern Australia will change in a warmer world.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.

Summary
Experimental facility for extreme air/sea interaction studies. The level of greenhouse gases in the atmosphere which cause global warming is greatly influenced by interactions at the air/sea interface. This infrastructure will allow in-depth studies of these interactions and contribute to much improved strategies to control greenhouse gases.

Eddy-resolving global ocean-sea ice modelling. This project aims to develop a world-class global ocean-sea ice model framework through a nationwide consortium. The resulting high resolution models are expected to provide the foundation for the next decade of Australian ocean-sea ice modelling capacity. This research should lead to improved ocean and sea ice prediction, ocean reanalyses, and climate projections, enhancing Australia's capacity to predict the ocean state on timescales of days to decades. This is expected to yield efficiencies in shipping, marine search and rescue and naval operations, and increase the accuracy of projected future changes in climate, sea level, ocean ecosystems and the cryosphere.Read moreRead less

Intense thunderstorms in the tropics and subtropics under global warming. This project aims to determine how the frequency of intense tropical and subtropical thunderstorms will change as a result of future global warming. Climate models project that the energy available to such storms will increase in the future, but the reasons for this increase in available energy, and the implications for thunderstorm activity, remain uncertain.

This project aims to determine how the frequency of intense tropical and subtropical thunderstorms will change as a result of future global warming. Climate models project that the energy available to such storms will increase in the future, but the reasons for this increase in available energy, and the implications for thunderstorm activity, remain uncertain. Using observations and high-resolution models, the project expects to generate new knowledge of the mechanisms driving changes in intense thunderstorm activity under climate change, and to provide more accurate projections of the frequency of intense thunderstorms in a warmer climate. This project should deliver benefits to sectors of the economy such as agriculture and transportation, which are significantly exposed to such hazards.Read moreRead less
Links between bushfires in Victoria and floods in Queensland. This project will investigate connections between bushfires in Victoria and floods in Queensland under the framework that atmospheric blocking can be thought of as a common link. High resolution runs using the Intergovernmental Panel on Climate Change future projections of the energetics of high impact weather will improve climate forecasts in sensitive coastal areas of the country.

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.
