Reconstructing changes in atmospheric circulation over the mid-latitudes of the Southern Hemisphere during the past 3000 years. The climate of the mid-latitudes of the southern hemisphere is of global significance and yet past changes have proved difficult to reconstruct due to the dearth of records. Working across the Southern Ocean region using tree rings, lake sediments and ice cores, the project will produce the first comprehensive reconstruction spanning the last 3000 years.

Summary
An Australian fluid-inclusion facility for climate-change science. Understanding past temperature and rainfall changes is essential for improving climate projections. The proposed facility will generate new palaeotemperature and palaeorainfall information from cave deposits, leading to a better understanding of natural climate variability and change.
Cyclones, storm tracks and precipitation over the globe, and their sensitivity to climate change. The project will explore in detail the intimate connection across the globe between storms, storm tracks and precipitation and the changes in these key aspects of weather and climate. Expected outcomes are an improved understanding of trends and outlooks for southern Australian and European weather and precipitation.

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.
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

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. This project will combine several powerful analysis techniques to answer some fundamental and currently unanswered questions on storm-related precipitation, including the extremes.

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
Weekly cycles of atmospheric parameters over Australia and the quantification of human influences on climate. Many human activities are organised on a seven-day cycle. The consequences of this might be expected to appear in the average variations of meteorological parameters across the week. This research will investigate these intra-week variations at many locations across Australia and will provide a critical insight into the human impact on climate.

This project aims to investigate the predictability of Australian extreme rainfall using the latest Bureau of Meteorology seasonal prediction system and new re-analyses and climate models. Extreme rainfall events in Australia are often associated with loss of life and damage to infrastructure and the environment, but some impacts can be mitigated with improved forecasting. This project will analyse influences of climate change and climate variability on seasonal-scale predictability of extreme rainfall. This will increase our understanding of the processes behind extreme rainfall events and where predictability arises from, and this would result in improvements in forecasting.Read moreRead less
Evaluating the weather in climate models - the relationship of dynamics and rainfall over Australia in current and future climates. Climate change will be experienced by society as a change in the day-to-day weather. This project will investigate the capabilities of modern climate models in simulating the weather with a particular focus on rainfall, and will provide guidance to the use of these models in projections of the future of Australia's climate.
