Summary
Dynamics, variability and change in Southern Ocean abyssal flows. Changes in the Southern Ocean abyssal circulation are linked with dramatic climate events, yet the associated dynamics are poorly understood. This project aims to determine the fundamental dynamic processes driving abyssal flows, and diagnose impacts of recent and projected climate change. The project also aims to bridge the large gap between conceptual and observational understanding of this vital limb of the ocean's overturning ....Dynamics, variability and change in Southern Ocean abyssal flows. Changes in the Southern Ocean abyssal circulation are linked with dramatic climate events, yet the associated dynamics are poorly understood. This project aims to determine the fundamental dynamic processes driving abyssal flows, and diagnose impacts of recent and projected climate change. The project also aims to bridge the large gap between conceptual and observational understanding of this vital limb of the ocean's overturning circulation. A significant innovation is that it will be the first study of the Southern Ocean abyss using realistic global-scale models capable of simulating all the key dynamic processes. Results will guide Southern Ocean observation programs, explain observed changes, and reduce uncertainties in climate projections.Read moreRead less

Summary
A new understanding of Antarctic ice melting. Melting of grounded ice in the Antarctic may play a key role in future global sea level rise and Earth's climate system. Ocean-ice interactions governing the rate of melting are not well understood and limited data leads to large uncertainties in the predictions of future melting rates. This project will undertake the first direct numerical simulations examining the complex dynamics of melting of ice-shelves in the presence of convection and turbulen ....A new understanding of Antarctic ice melting. Melting of grounded ice in the Antarctic may play a key role in future global sea level rise and Earth's climate system. Ocean-ice interactions governing the rate of melting are not well understood and limited data leads to large uncertainties in the predictions of future melting rates. This project will undertake the first direct numerical simulations examining the complex dynamics of melting of ice-shelves in the presence of convection and turbulence, while translating the results to improve ocean models. By calculating the sensitivity of melting rate to surrounding ocean conditions, the project will develop the knowledge required to better predict future melting rates.Read moreRead less

Summary
Landscape-climate disequilibrium in dune fields. This project aims to predict how wind-blown landscapes respond to changes in climate. This project expects to use novel experiments and theoretical advances to meet this aim, then apply the prediction to the dune fields which cover a third of Australia's surface to generate new knowledge on what climate shaped them in the past, and how they will respond to anthropogenic climate change.

This project aims to predict how wind-blown landscapes respond to changes in climate. This project expects to use novel experiments and theoretical advances to meet this aim, then apply the prediction to the dune fields which cover a third of Australia's surface to generate new knowledge on what climate shaped them in the past, and how they will respond to anthropogenic climate change. Expected outcomes of this project will strengthen collaboration with discipline-leading international researchers and develop a globally-unique laboratory experimental capability in Australia. This should provide significant benefits to understanding environmental change in Australia by vastly improving predictions of dune-field response to future climate.Read moreRead less

Summary
Inter-ocean exchange around Australia and its relation to regional and global climate. The flow of water from the Pacific to the Indian Ocean is important to both regional and global climate. Most of the water flows through the Indonesian Archipelago, but there is also a westward flow south of Tasmania. We will study the dynamics of this inter-ocean exchange and investigate how it impacts regional climate and marine ecosystems.

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.

Summary
The further back we look, the further forward we can see: 1,000 years of past climate to help predict future climate change in Australia. Reconstructing 1,000 years of Australia's past climate will greatly extend our understanding of natural climate variability currently estimated from weather observations. For the first time, Australian climate variations over the last millennium will be used to assess the accuracy of climate model simulations for our region.

Extratropical Cyclones and their Associated Precipitation: Understanding, Model Evaluation, and Future Projections. Storms and their associated frontal systems are responsible for producing most of the precipitation in mid-latitudes.

Storms and their associated frontal systems are responsible for producing most of the precipitation in mid-latitudes. This project will combine several powerful analysis techniques to answer some fundamental and currently unanswered questions on storm-related precipitation, including the extremes. State-of-the-art climate models, our main tool in projecting future climate changes, will then be evaluated to ensure they are able to capture the essential processes of storm-related precipitation that have been elucidated. This is essential to increase confidence in the projection of storm changes and their related precipitation, thereby providing better information to water managers.Read moreRead less

Summary
Will an improved land surface model enhance seasonal prediction of drought? This project aims to increase the predictability of seasonal droughts that cause major socio-economic losses in rural Australia. The capacity to predict drought, and in particular its impacts on the land, is currently limited by the low skill of forecast models. Using novel observations, the project expects to quantify the vulnerability of Australian agricultural lands to seasonal droughts.

This project aims to increase the predictability of seasonal droughts that cause major socio-economic losses in rural Australia. The capacity to predict drought, and in particular its impacts on the land, is currently limited by the low skill of forecast models. Using novel observations, the project expects to quantify the vulnerability of Australian agricultural lands to seasonal droughts. The new knowledge will then be used to modify land processes in the Bureau of Meteorology’s seasonal prediction system to better reflect Australian conditions. This project is expected to improve forecasts of high impact droughts, crucial to mitigate socio-economic risks, and should benefit decision-making in agriculture and other industries.Read moreRead less

Rising atmospheric CO2 and the associated changes in rainfall regimes are rapidly reshaping how Australia’s forest ecosystems function and underpin our daily life. Whether Australia’s native Eucalyptus trees can withstand the impacts of climate extremes such as drought and heat under rising CO2 is a crucial question that this project aims to resolve.

Rising atmospheric CO2 and the associated changes in rainfall regimes are rapidly reshaping how Australia’s forest ecosystems function and underpin our daily life. Whether Australia’s native Eucalyptus trees can withstand the impacts of climate extremes such as drought and heat under rising CO2 is a crucial question that this project aims to resolve. Using an innovative framework that integrates novel knowledge, data assimilation and ecosystem modelling, this project will provide critically needed evidence to disentangle the multifaceted impacts of climate change to Eucalyptus trees. This will help reduce the predictive uncertainty in assessing the vulnerability and resilience of Eucalyptus forests in the changing Australian landscape. Read moreRead less
