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.
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

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

Summary
Mixing and air-sea coupling in the Pacific: Toward better El Nino forecasts. The Tropical Pacific drives significant year-to-year variability in Australian rainfall and climate extremes. However, tropical climate predictions are severely limited due to systematic biases in numerical climate models. Using new techniques and leveraging international collaborations, this project aims to transform our ability to simulate tropical Pacific climate through a new understanding of key air-sea interaction ....Mixing and air-sea coupling in the Pacific: Toward better El Nino forecasts. The Tropical Pacific drives significant year-to-year variability in Australian rainfall and climate extremes. However, tropical climate predictions are severely limited due to systematic biases in numerical climate models. Using new techniques and leveraging international collaborations, this project aims to transform our ability to simulate tropical Pacific climate through a new understanding of key air-sea interaction and ocean mixing processes. Expected outcomes include a better representation of tropical climate in the Australian climate model and improved seasonal to interannual predictive capability. These improved predictions will give communities more time to prepare for extreme events such as droughts, heatwaves and bushfires.Read moreRead less

Eddy-resolving global ocean-sea ice modelling. This project aims to develop a world-class global ocean-sea ice model framework through a nationwide consortium. The resulting high resolution models are expected to provide the foundation for the next decade of Australian ocean-sea ice modelling capacity. This research should lead to improved ocean and sea ice prediction, ocean reanalyses, and climate projections, enhancing Australia's capacity to predict the ocean state on timescales of days to decades. This is expected to yield efficiencies in shipping, marine search and rescue and naval operations, and increase the accuracy of projected future changes in climate, sea level, ocean ecosystems and the cryosphere.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.

Summary
Understanding the termination of El Nino-Southern Oscillation events. Australia's climate is extreme, with significant drought and flooding events driven by cycles of the El Nino-Southern Oscillation (ENSO). This study will improve our understanding of the termination of ENSO events and lead to better inter-seasonal climate forecasting, aiding the sectors reliant on accurate climate prediction.
Australian climate extremes and predictability in a changing CO2 world: the unique role of the Southern Hemisphere extratropical ocean-atmosphere. Australia's climate is extreme, with harsh droughts, severe bushfire seasons, climate change, soil loss, and salinity all posing potentially enormous socio-economic challenges over the next fifty years. Research into climate variability, extremes, and predictability is thus highly significant for Australia, and will underpin efforts to protect our bio ....Australian climate extremes and predictability in a changing CO2 world: the unique role of the Southern Hemisphere extratropical ocean-atmosphere. Australia's climate is extreme, with harsh droughts, severe bushfire seasons, climate change, soil loss, and salinity all posing potentially enormous socio-economic challenges over the next fifty years. Research into climate variability, extremes, and predictability is thus highly significant for Australia, and will underpin efforts to protect our biodiversity and ensure the nation's environmental sustainability. We propose to launch a major new initiative in extratropical climate analysis. This work will have significant benefits for the many sectors of society reliant on interseasonal-interannual climate prediction. Prominent examples include agriculture, energy, freshwater supply, bushfire control, air quality, health, and tourism.Read moreRead less

This project aims to improve our understanding of the role of convection on the Antarctic margins using a high-resolution, cutting-edge numerical approach. Convection is an important, but poorly understood oceanic process, which diverts heat away from the melting Antarctic ice shelves by transporting cold and salty water from the ocean surface to depth. The project outcomes will be new knowledge of the physics from novel numerical models and theory, supported by insights from observations and model parameterisations. This timely research will improve prediction of sea level rise due to a changing Antarctica and enhance our ability to adapt to future climate scenarios, providing significant environmental and health benefits to Australians.Read moreRead less
