Local climate changes caused by large bushfire burnt areas. This project aims to quantify the impact on local climate produced by large burnt areas after extreme bushfires. This project expects to generate new knowledge on these previously unexplored fire-scar induced changes to local climate.

This project aims to quantify the impact on local climate produced by large burnt areas after extreme bushfires. This project expects to generate new knowledge on these previously unexplored fire-scar induced changes to local climate. It will extend an innovative approach that combines satellite based earth observation with very high resolution regional climate modelling to quantify the impacts on land-atmosphere feedbacks and local climate. Expected outcomes of this project include enhanced methods to quantify local climate changes after extreme fires and their effect on vegetation recovery. This should provide significant benefits to the planning for, and management of, vegetation recovery after extreme fires.Read moreRead less
An ensemble approach to studying the ocean's role in climate change. Using a newly-developed ocean model that harnesses the power of graphical processing units (GPUs) instead of the common central processing units (CPUs) we can run global ocean simulations at 1/50th the cost. Utilising this speed up, we aim to pioneer a modelling framework to perform ensembles of eddy-resolving global ocean simulations under various climate-change scenarios. This ensemble approach will enable us to separate the ....An ensemble approach to studying the ocean's role in climate change. Using a newly-developed ocean model that harnesses the power of graphical processing units (GPUs) instead of the common central processing units (CPUs) we can run global ocean simulations at 1/50th the cost. Utilising this speed up, we aim to pioneer a modelling framework to perform ensembles of eddy-resolving global ocean simulations under various climate-change scenarios. This ensemble approach will enable us to separate the changes we see in future projections that are due to climate change from the changes that occur in the due to the natural variations of the climate system. The project's outcomes will increase our confidence in future climate change projections, including ocean heat uptake, and sea level rise.Read moreRead less

This Centre aims to determine how Australia’s weather is being reshaped by climate change. Through a fusion of innovative analyses of observations and fundamental science advances, alongside the development of ultra-high resolution climate models, the Centre looks to address climate science’s grand challenge in anticipating the likely weather patterns of a warmer world. The Centre strives to transform climate research by focussing on what matters most to making critical adaptation and mitigation decisions – weather change. The Centre aspires to provide Australia with the knowledge, technology, and human capital for robust evidence-based decision-making in response to future weather changes in our region and to harness weather as a resource.Read moreRead less
A Holocene history of rainfall extremes for the South Pacific . The project aims to generate the longest ever record of rainfall extremes in the Southern Hemisphere (11,700 years) that will be used to update probabilistic recurrence intervals and inform future risks in a warming world. We will apply a palaeoclimate approach to the science of extreme events by using proxy data from stalagmites to investigate natural rainfall variability during the Holocene. Combined with state of the art Global C ....A Holocene history of rainfall extremes for the South Pacific . The project aims to generate the longest ever record of rainfall extremes in the Southern Hemisphere (11,700 years) that will be used to update probabilistic recurrence intervals and inform future risks in a warming world. We will apply a palaeoclimate approach to the science of extreme events by using proxy data from stalagmites to investigate natural rainfall variability during the Holocene. Combined with state of the art Global Climate Model simulations for three major climate events of the Holocene, we will identify mechanisms of long term shifts in heavy rainfall events. The project will provide significant benefits for Australia and the Pacific islands in terms of prediction and preparedness for deluges like we experienced in 2022.Read moreRead less

Summary
How will Pacific climate variability impact Australia in a warming world? Temperature variability in the Pacific Ocean is characterised by El Niño and La Niña (year-to-year variations) and the Interdecadal Pacific Oscillation (decadal variations). These phenomena are primary drivers of Australian temperature and rainfall. Leveraging new tools and methods, including Single Model Initial-Condition Large Ensembles, this project will investigate drivers of these phenomena, and their impacts on Austr ....How will Pacific climate variability impact Australia in a warming world? Temperature variability in the Pacific Ocean is characterised by El Niño and La Niña (year-to-year variations) and the Interdecadal Pacific Oscillation (decadal variations). These phenomena are primary drivers of Australian temperature and rainfall. Leveraging new tools and methods, including Single Model Initial-Condition Large Ensembles, this project will investigate drivers of these phenomena, and their impacts on Australia in a warming world. Outcomes include the quantification of how these climate phenomena modulate extreme weather events, and an understanding of how Indian and Atlantic Ocean warming affects the Pacific region. This will improve the prediction of extreme events, which is critical for preparation for their impacts.Read moreRead less

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
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
