ARC Centre of Excellence for Climate Extremes. This Centre aims to transform understanding of past and present climate extremes and revolutionise Australia’s capability to predict them into the future. Climate extremes cost Australia up to $4 billion a year and will intensify over coming decades. This Centre’s blue-sky research will discover processes that explain the behaviour of present and future climate extremes.

Climate extremes cost Australia up to $4 billion a year and will intensify over coming decades. This Centre’s blue-sky research will discover processes that explain the behaviour of present and future climate extremes. It will use its researchers, data, modelling, collaboration, graduate programme and early career researcher mentoring to transform Australia’s capacity to predict climate extremes. This research is expected to make Australia more resilient to climate extremes and minimise risks from climate extremes to the Australian environment, society and economy.Read moreRead less
Predicting soil loss from wind erosion, using an integrated, high resolution, land surface data assimilation-modelling system. Australia is an ancient, dry, continent. Soil losses from wind erosion are practically irreversible. Prevention of wind erosion, especially in agricultural areas, is a major challenge to agricultural communities and land management organisations. For continental and regional scale assessment of wind erosion potential, the high-resolution integrated wind erosion modelling ....Predicting soil loss from wind erosion, using an integrated, high resolution, land surface data assimilation-modelling system. Australia is an ancient, dry, continent. Soil losses from wind erosion are practically irreversible. Prevention of wind erosion, especially in agricultural areas, is a major challenge to agricultural communities and land management organisations. For continental and regional scale assessment of wind erosion potential, the high-resolution integrated wind erosion modelling system developed here is a powerful tool. The system will identify areas prone to soil erosion and provide a solid scientific basis for strategic and practical measures for wind erosion prevention. The proposal allows the CIs to continue to play a leading international role in this National Research Priority area.Read moreRead less
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).

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 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
Using Advances in Bayesian Statistics to Estimate Australian Rainfall Variations in a Climate Change World. Modelling changes to rainfall patterns answers many important questions about changes in Australia's climate. This is essential to protecting our biodiversity and ensuring Australia's environmental sustainability.

Modelling changes to rainfall patterns answers many important questions about changes in Australia's climate. This is essential to protecting our biodiversity and ensuring Australia's environmental sustainability. The project will address such issues as the extent to which the entire distribution of daily rainfall has changed over time, which areas of Australia have been most affected by this change and to what extent are these changes related to global climate indices. The latest advances in Bayesian statistics will be used to introduce flexibility and complexity into the model.Read moreRead less
Will East Coast Lows change in frequency or intensity in the future? East Coast Lows, the largest storms on the south-east coast of Australia, produce both large benefits and losses for this highly populated region of the country. An urgent national priority exists to understand the driving mechanisms for these events and to quantify how the frequency and intensity of these systems will change due to climate change.
Has rainfall become more variable or extreme? The trends and variability of global daily rainfall are uncertain. By tackling data shortcomings and the scaling issues that exist between observations and models, this project aims to produce the first well-constrained long-term assessment of the variability and trends in daily rainfall over land. Using extreme value analysis on the resulting data would allow the exploration of the sensitivity of rainfall extremes to grid resolution, interpolation m ....Has rainfall become more variable or extreme? The trends and variability of global daily rainfall are uncertain. By tackling data shortcomings and the scaling issues that exist between observations and models, this project aims to produce the first well-constrained long-term assessment of the variability and trends in daily rainfall over land. Using extreme value analysis on the resulting data would allow the exploration of the sensitivity of rainfall extremes to grid resolution, interpolation method and order of operation on an unprecedented grand scale. Ultimately, this means that improved return period estimates could be calculated for the types of events that could lead to flooding. Understanding how, where and why it rains is vital for enabling sound decisions to be made by our planners and policy-makers.Read moreRead less

This project aims to employ targeted field observations, numerical simulations and new satellite capabilities to identify the dynamical and microphysical mechanisms that enhance and redistribute precipitation across the alpine regions of south eastern Australia and Tasmania. These observations will be used to evaluate operational numerical weather simulations specifically focusing on quantitative precipitation forecasts and estimates. The observations will also be used to extend known biases in the national gridded precipitation analysis that are a result of the complex mountain terrain. This identification of the physical processes that enhance and redistribute precipitation over the alpine regions across south east Australia and Tasmania will lead to better precipitation estimates and forecasts and better water management.Read moreRead less
