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.
WAKE FLOWS WITH UPSTREAM TURBULENCE IN MARINE, ATMOSPHERIC AND BUILT ENVIRONMENTS. Through improved understanding of turbulent wakes the project will have applications across aeronautics and hydrodynamics, leading to more efficient engineering designs to reduce flow drag. In marine environments our findings will improve coastal ocean models and the prediction of pollutant dispersal, nutrient fluxes and sediment transport, and contribute to the management of biological productivity (NRP 1.5).

In marine environments our findings will improve coastal ocean models and the prediction of pollutant dispersal, nutrient fluxes and sediment transport, and contribute to the management of biological productivity (NRP 1.5). In the atmospheric boundary layer, the results will assist planners to improve wind environments near large buildings or clusters of buildings, benefiting the safety of aircraft at takeoff and landing. The project will develop collaboration and help maintain the strength of Australian research in environmental flows.Read moreRead less
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.

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
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

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.
Sentencing and public confidence: public perceptions and the role of the public in sentencing practice and policy. Public confidence is critical to the effective operation of the criminal justice system. This project will generate much needed current national data on public attitudes about sentencing. It examines avenues for the incorporation of public opinion into sentencing policy and processes, and provides accurate measures of the factors involved. The results will enable governments to res ....Sentencing and public confidence: public perceptions and the role of the public in sentencing practice and policy. Public confidence is critical to the effective operation of the criminal justice system. This project will generate much needed current national data on public attitudes about sentencing. It examines avenues for the incorporation of public opinion into sentencing policy and processes, and provides accurate measures of the factors involved. The results will enable governments to respond to periodic crises in public confidence in constructive and informed ways, rather than act in response to law and order rhetoric, linked with harsh sentencing regimes, and costly and potentially unnecessary increases in incarceration rates.Read moreRead less
The energetics and dynamics of chemical reactions of polyatomic molecules involving multiple electronic states. This project will produce, from first principles, the first quantitatively accurate computer simulations of chemical reactions which involve several atoms and multiple electronic states. Many of the most important chemical reactions in the atmosphere (and elsewhere) involve changing both the shape of the molecules and their electronic structure. Many of these reactions are difficult to ....The energetics and dynamics of chemical reactions of polyatomic molecules involving multiple electronic states. This project will produce, from first principles, the first quantitatively accurate computer simulations of chemical reactions which involve several atoms and multiple electronic states. Many of the most important chemical reactions in the atmosphere (and elsewhere) involve changing both the shape of the molecules and their electronic structure. Many of these reactions are difficult to study in the laboratory, and consequently computer simulation is an essential component of the study of such reactions. U nderstanding how these reactions occur, and how fast they proceed, are important to our understanding of the dynamics of the atmosphere and other large scale reactors.Read moreRead less
