This project aims to provide more accurate information on the human signal behind heatwaves and their impacts, by deriving a comprehensive approach of the detection and attribution of climate extremes. The project expects to generate robust estimates of the human signal behind high-impact events, and an innovative, versatile methodology that can be applied to any extreme event and its impacts. With the specific application to Australian heatwave impacts on human health, key knowledge should support more targeted and accurate mitigation policies, minimising the strain on resources when future heatwaves occur. This should help in safeguarding future generations from deadly impacts of heatwaves.Read moreRead less

Our capacity to assess the threat of climate change is undermined by an unacceptable level of uncertainty in the understanding and modelling of regional climates. The Centre will undertake world-class research targeting identified weaknesses in the physical, chemical and biological components of the climate system. We will engage and nurture graduate students and postdoctoral follows through a program of graduate training and mentoring to permanently transform our understanding of climate systems science particularly for the Australian region. The key outcome will be a dramatic enhancement in national capacity to understand and project the scale of future regional climate change.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

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

Decadal climate variability: Mechanisms, interactions and effects. This project aims to study the processes underlying decadal climate variability, through increasingly complex models, underpinned by observations. Climate variations on time scales of years, decades and longer affect Australia, with potentially devastating effects on agriculture, water supply, bushfires and health.

This project aims to study the processes underlying decadal climate variability, through increasingly complex models, underpinned by observations. Climate variations on time scales of years, decades and longer affect Australia, with potentially devastating effects on agriculture, water supply, bushfires and health. Improved climate prediction on decadal time scales is urgently needed, but limited understanding of the system’s natural variability hampers progress. This knowledge will reduce uncertainty in near term climate projections, allowing more informed decision making about adaptation on the regional scale, particularly for sectors such as agriculture, health, water and ecosystem management (including bushfire control).Read moreRead less

Connecting big data with high performance computing for climate science: The ARC Centre of Excellence for Climate System Science is a key user of the National Computational Infrastructure facility (NCI). This research requires massive data integrated with high performance computing in an operational facility. Fast disk capacity that is simultaneously connected to NCI long-term storage, cloud and high performance computing severely limits use of the NCI. To resolve this limitation, 1.7 petabytes of storage will be installed to transform the efficiency of the facility. This will enable more ambitious science to be undertaken. This investment will be used to launch a transformation from petascale to exascale problems and communicate the lessons learned to other research communities in Australia.Read moreRead less

This project aims to determine the environmental factors controlling the intensity of extreme East Coast Lows and how their intensity responds to global warming conditions. East Coast Lows are responsible for much of the high-impact weather affecting the east coast of Australia. Understanding the causes behind future climate changes is critical to provide confidence in future projections. This project will use high-resolution climate models that can realistically simulate all the key dynamic processes including atmosphere-ocean interactions. Expected outcomes are adaptation strategies to mitigate the future effect of East Coast Lows on coastal fresh water resources, flooding and erosion.Read moreRead less
Improving the credibility of regional sea level rise projections. Anthropogenic sea level rise is expected to inundate low-lying islands and coastlines around the world, with multiple model projections suggesting that changes in wind patterns will lead to larger than average sea level rise along Australia’s east coast and in neighbouring small island nations. Confidence in projections of this spatial sea level rise variability is low, however, due to a strong mismatch between patterns of observe ....Improving the credibility of regional sea level rise projections. Anthropogenic sea level rise is expected to inundate low-lying islands and coastlines around the world, with multiple model projections suggesting that changes in wind patterns will lead to larger than average sea level rise along Australia’s east coast and in neighbouring small island nations. Confidence in projections of this spatial sea level rise variability is low, however, due to a strong mismatch between patterns of observed and model-projected sea level rise in recent decades. This work will use a newly developed climate model hierarchy and innovative experimental design to determine the cause of this discrepancy and will produce more credible regional sea level rise projections by clarifying and reducing projection uncertainty.

This project aims to implement a regional, coupled atmosphere and ocean model, to determine under what circumstance ocean-atmosphere interactions are critical. Regional high-resolution atmosphere models are routinely used to provide projections of climate at the local scales needed by decision makers. However, these tools neglect the fine-scale interactions between ocean and atmosphere that can significantly modify conditions around coastal or island regions. This project intends to deliver the first high-resolution projections of both ocean and atmosphere off eastern Australia to understand how small-scale ocean and atmosphere processes and their interactions affect changes in extreme rainfall, marine heat waves and ocean circulation.Read moreRead less
