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.
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.

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.

Facilities for Atmospheric Boundary Layer Evaluation and Testing. This proposal aims to establish state-of-the-art stationary and mobile facilities for atmospheric wind, dust and plume measurements with unique capability to quantify the effect of climate change, surface topography and urbanisation on near-surface microclimate where humans live.

This proposal aims to establish state-of-the-art stationary and mobile facilities for atmospheric wind, dust and plume measurements with unique capability to quantify the effect of climate change, surface topography and urbanisation on near-surface microclimate where humans live. To better predict microclimate, mitigate air pollution impacts and exploit local conditions for improved urban planning and agricultural yield, high quality observations of the near-surface atmosphere at fine temporal and spatial resolutions are required. The proposed Facilities for Atmospheric Boundary Layer Evaluation and Testing (FABLET) will advance Australia’s capability to make these difficult measurements of atmospheric boundary layer.Read moreRead less
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

The analysis of comprehensive extremes datasets, comprising global observations and output of multi-model simulations, will greatly improve our ability to answer fundamental questions about the nature and variability of extreme climatic events. This project also ensures the government's continued commitment to managing the risks associated with extreme events as an urgent national priority. It represents a landmark opportunity for Australian leadership of an international collaboration between some of the world's leading climate scientists and climate data and modelling centres.Read moreRead less
A theory for the vertical structure of tropical atmospheric circulations. The vertical structure of atmospheric circulations is a key determinant of rainfall patterns and climate, but model projections do not agree on how it will change in a warmer world.

The vertical structure of atmospheric circulations is a key determinant of rainfall patterns and climate, but model projections do not agree on how it will change in a warmer world. This project aims to discover the processes that control the vertical structure of tropical atmospheric circulations. It will combine theory development, analysis of observations, and targeted modelling to generate new knowledge of the mechanisms affecting atmospheric circulations as the climate changes. This will allow for process-based identification of the most reliable climate models, facilitating increased confidence in future projections. More accurate tropical climate projections will benefit decision making for resource management in northern Australia.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.
When the ice melts: a new perspective on the causes of Quaternary glacial terminations. The project will assemble an unprecedented palaeoclimate time series extending back to 1.2 million years ago that will allow marine and ice core records to be placed onto an absolute time scale. This will allow testing of fundamental hypotheses on why the Earth's climate shifts from glacial to interglacial states, with flow-on effects to climate models.
