Enhancing Australia’s capacity to manage climate variability and climate extremes in a changing climate
Heatwaves, floods and droughts in Australia cause high economic, agricultural and human costs. Managing the risks and reducing the costs associated with climate variability and extremes requires a transformation in our current understanding of the influence of climate change now and into the future.
We’re analysing past climate variability and extremes, and projections of the El Niño–Southern Oscillation’s impact on drought, to improve our understanding of the driving mechanisms and processes. Our focus is on longer timescale extremes, such as extended heatwaves and droughts, and the historical record of tropical cyclones. This research will inform the development of robust projections that will help Australia prepare for and respond to climate variability, extremes and change in the future.

This project is contributing to meeting the following climate challenges:
Modelling improvements developed in this project will enhance the quality of climate projections that are available to water managers and planners.
Agricultural and environmental managers will be able to use projections developed from work in this project to make more effective management decisions.
Research undertaken in this project will allow for better simulation of extreme events in climate projections, making them a more useful tool for governments and other agencies that are responsible for preparing for and managing the response to natural disasters.
