Improving understanding of climate change and its impacts in Australia through detection and attribution of climate change. This research will quantify the contribution to Australian regional climate change due to greenhouse gases, which will assist policymakers in reaching decisions about policies on emission reductions or adaptation to greenhouse climate change.

This research will quantify the contribution to Australian regional climate change due to greenhouse gases, which will assist policymakers in reaching decisions about policies on emission reductions or adaptation to greenhouse climate change. Improved estimates of uncertainties in future regional climate changes due to increasing greenhouse gases will allow better quantification of their likely impacts, estimation of the costs or maximising any benefits from regional climate changes. Through collaboration with the Bureau of Meteorology and CSIRO, this research enhances Australia's capabilities in diagnostic analysis of climate variability and change, and aids the development and evaluation of new Australian climate models.

Precipitation-groundwater interactions over eastern Australia: climate change impacts at multiple scales. Most surface water in the Murray-Darling Basin is used for agricultural activity, and groundwater extraction is accelerating. We cannot yet predict how these water resources will be affected by climate change, partly because Australian climate models do not represent key interactions between small and large scale rainfall changes, and interactions between ground water, the land surface and t ....Precipitation-groundwater interactions over eastern Australia: climate change impacts at multiple scales. Most surface water in the Murray-Darling Basin is used for agricultural activity, and groundwater extraction is accelerating. We cannot yet predict how these water resources will be affected by climate change, partly because Australian climate models do not represent key interactions between small and large scale rainfall changes, and interactions between ground water, the land surface and the atmosphere. This project will produce the first climate simulations that explicitly include these interactions. This will allow a better understanding of future changes to groundwater resources. This understanding will help us plan ahead, and enable new research to help Australia maintain food security in an uncertain future.Read moreRead less
Radar Studies of Rainfall with Applications to Forecasting. Weather watch radars are used to predict severe weather events, with echo strengths depending on the number of rain drops in the beam. With suitable calibration the echo intensities can be used to predict rainfall rates. In 2005 the Bureau of Meteorology will establish a new weather radar near Adelaide. We will compare rainfall estimates made with the new radar with results from a VHF profiler that accurately measures rain drop distribu ....Radar Studies of Rainfall with Applications to Forecasting. Weather watch radars are used to predict severe weather events, with echo strengths depending on the number of rain drops in the beam. With suitable calibration the echo intensities can be used to predict rainfall rates. In 2005 the Bureau of Meteorology will establish a new weather radar near Adelaide. We will compare rainfall estimates made with the new radar with results from a VHF profiler that accurately measures rain drop distributions and rainfall. The aim is to test the weather radar estimates of rainfall rates and their uncertainties. Outcomes will have applications in flood forecasting and hydrology.Read moreRead less
