This release is to advise the community that an ACCESS Oversight Committee has been formed initially comprising Christian Jakob, Rachel Law, Helen Cleugh, Andy Pitman, Tony Hirst, Peter May, David Karoly and Ben Evans. Terms of reference have been agreed to by the group and can be found at the end of this document.

The Centre has had a busy four months with its researchers having an impact nationally and internationally. The Centre has achieved some foundation and enabling research around the delivery of data, and a series of new research discoveries, that will play an important role in climate extremes research for some years. And Centre researchers are once again the winners of some major awards.

This student project will focus on spatially correlated events in Australia that occurred in the past 30 to 40 years. Using observations over this time period the student will catalogue past compound events; assess possible trends in their occurrence; check for preferred spatial correlation patterns; and assess if these were accurately reproduced in reanalysis products (e.g. BARRA, ERA-5 and/or ERA-Interim).

The Postdoctoral Research Associate will work on a new ARC-funded project exploring how vulnerable Australia’s eucalypts are to future droughts. This project will combine data-synthesis, experimental manipulation and modelling to deliver new process-orientated insight into the response of eucalyptus trees to projected changes in the frequency, magnitude and duration of future droughts across Australia.

New CLEX research finds land cover misclassifications over South East Asia based on remote sensing products have negligible impact on the outcomes of climate model experiments. However, land cover experiments that incorporate uncertainties must use large numbers of simulations to get robust results for rainfall and air temperature.

How wet the soil is before a storm can determine the amount of rain that falls. This research also produced some interesting findings for rainfall in Australia.

This study illustrates how future uncertainty of climate models in predicting hot extremes is controlled by two factors, both related to amplification of hot extremes through land-atmosphere interactions

The Australian FLUXNET data provide perhaps the world’s most valuable observations for building and evaluating the land models needed for projecting future droughts and heatwaves.

By employing an atmosphere-only version of ACCESS, CLEX researchers generated multiple sea surface temperature patterns of the same El Nino and La Nina events, and assessed how this influenced heatwaves over various Australian regions.
