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.

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 in our predictions of tropical cyclone incidence in a future, changed climate.Read moreRead less
Ocean heat content change and its impact on sea level. This project aims to improve projections of possible sea level changes. Sea level rise is among the most significant potential impacts of transient climate change around the world. Poor understanding of the way in which heat is absorbed at the sea surface and distributed by ocean circulation is a leading source of uncertainty in projections of global surface temperature and regional sea level rise by the end of this century. This project aim ....Ocean heat content change and its impact on sea level. This project aims to improve projections of possible sea level changes. Sea level rise is among the most significant potential impacts of transient climate change around the world. Poor understanding of the way in which heat is absorbed at the sea surface and distributed by ocean circulation is a leading source of uncertainty in projections of global surface temperature and regional sea level rise by the end of this century. This project aims to apply novel observational methods, complimented by numerical modelling, to quantify the drivers of recent change. This project expects to transform our ability to predict how ocean temperature and sea level will change in the future.Read moreRead less
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.
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.
Demographic consequences of Asian disasters: family dynamics, social capital and migration patterns. This study of the long term demographic consequences of Asian disasters will contribute to development of more effective governmental policies on disaster mitigation, preparedness and reconstruction/recovery, thus assisting to reduce the human and material losses from natural disasters.
Aqueous fluids in the deep earth. This project aims to improve our understanding of the role of fluids in controlling exchanges between the deep Earth, shallow rocks, and atmosphere. The project expects to investigate some of the key weaknesses in the thermodynamic models that are used to predict the behaviour of sulphur, carbon and metals in fluids at high pressure and temperature by using recent advances in computational and experimental (geo)chemistry. Integrated in large-scale geodynamic mod ....Aqueous fluids in the deep earth. This project aims to improve our understanding of the role of fluids in controlling exchanges between the deep Earth, shallow rocks, and atmosphere. The project expects to investigate some of the key weaknesses in the thermodynamic models that are used to predict the behaviour of sulphur, carbon and metals in fluids at high pressure and temperature by using recent advances in computational and experimental (geo)chemistry. Integrated in large-scale geodynamic models, the more reliable predictions will provide a more realistic assessment of the role of sulphur in controlling metal endowment and atmospheric chemistry through geological times. This should provide a useful guide for mineral exploration and planetary science.Read moreRead less
Understanding climate and harvest induced changes in fish life histories. This project aims to quantify the cumulative impacts of harvest and climate change across marine fishes and ecosystems. The project expects to generate new knowledge in this area by coupling the rich biological information archived in fish ear bones, with targeted multi-generation experiments and predictive modelling.

This project aims to quantify the cumulative impacts of harvest and climate change across marine fishes and ecosystems. The project expects to generate new knowledge in this area by coupling the rich biological information archived in fish ear bones, with targeted multi-generation experiments and predictive modelling. Expected outcomes include fundamental insights into how human-induced environmental change affects fish growth and maturation, and a subsequent critical evaluation of the sensitivity of fisheries models to trends in these life-history traits. This should provide significant benefits to fisheries and ecosystem management, ensuring they remain productive and resilient in a time of rapid environmental change.Read moreRead less
The Southern Ocean boundary layer: winds, turbulence, sea spray and clouds. Both satellite products and climate models have large biases in the energy and water budgets over the Southern Ocean (SO). This is a direct consequence of a poor understanding of the structure and dynamics of the SO atmospheric boundary layer, which has arisen from an inability to make the necessary observations in this harsh environment. Due to the availability of new Australian research infrastructure, large steps forw ....The Southern Ocean boundary layer: winds, turbulence, sea spray and clouds. Both satellite products and climate models have large biases in the energy and water budgets over the Southern Ocean (SO). This is a direct consequence of a poor understanding of the structure and dynamics of the SO atmospheric boundary layer, which has arisen from an inability to make the necessary observations in this harsh environment. Due to the availability of new Australian research infrastructure, large steps forward are now possible with modest investment. This project will conduct and combine observations from the recently acquired marine vessel, RV Investigator, and the collocated airborne and surface observations to understand the structure and evolution of the unique, pristine SO boundary layer and to evaluate satellites and climate models.Read moreRead less
Drivers of phenotypic evolution in a vulnerable alpine ecosystem. This project aims to deliver a comprehensive, integrated understanding of the capacity for resilience and drivers of response of highly vulnerable alpine species and communities to climate change. The project aims to determine how communities of interacting alpine plants, soil invertebrates and microbes can cope with or evolve to novel climatic conditions. The mountains are water towers critical to power supply and Australia's agr ....Drivers of phenotypic evolution in a vulnerable alpine ecosystem. This project aims to deliver a comprehensive, integrated understanding of the capacity for resilience and drivers of response of highly vulnerable alpine species and communities to climate change. The project aims to determine how communities of interacting alpine plants, soil invertebrates and microbes can cope with or evolve to novel climatic conditions. The mountains are water towers critical to power supply and Australia's agricultural productivity. Understanding physiological tolerance and the potential for rapid evolutionary responses of plants, animals and communities is necessary to predict impacts of climate change on the future productivity of the vulnerable Australian Alps and to provide novel options for climate adaptation.

The link between the deep Earth and its dynamic surface. Modelling the two-way interaction of plate tectonics with the actions of erosion and sedimentation gives a fundamentally new view of the dynamics of our planet and the importance of the surface on the deep interior. It will improve our understanding of the formation of sedimentary basins, their evolution and their preservation over geological time.
