Drought is a major risk to Australia with extended periods of drought affecting our social, economic and environmental systems. The newly released report by the Intergovernmental Panel on Climate Change contains significant new assessments of the science and future projections of drought.

As part of CLEX’s engagement with the agricultural sector, Chief Investigators Ailie Gallant and Andrea Taschetto presented an overview of some of the Centre’s relevant research interests to the monthly meeting of the Forewarned is Forearmed Community of Practice (FWFACoP) group in June 2021.
Until now, flash drought research has been on the regional scale and has been limited to observations and reanalyses. CLEX researchers have been the first to examine flash drought in climate models.
With the drama and instability of 2020, many of our ECRs have faced unprecedented challenges including loneliness, homesickness and the mounting uncertainties for their future careers. That latter concern may be why the majority of ECRs wanted this year's virtual ECR workshop to focus on the Future in academia and planning your research career.
CLEX researchers examined the uncertainties of the input data of three commonly used drought indices, with the data coming from different sources, including observations and reanalysis. The ability of these indices to detect drought was assessed against soil moisture from multiple global land surface models.
Drought can unfold on sub-seasonal to seasonal time scales, meaning weeks to months, posing a particular risk to the agricultural sector. This type of drought has recently been recognized and given the name “flash drought”.
The CLEX Knowledge Brokerage Team (KBT) is now well and truly bedded down after coming into existence in October 2018. Team leader Ian Macadam has visited each of the CLEX university nodes and has attempted to answer the question on everyone’s lips “So what is a knowledge broker anyway?”.
A successful workshop on the science of multi-year drought was recently held at Monash University in Melbourne, where 50 experts from Australia, and small number of experts from the UK and the US, met to discuss what we know about the science of these droughts in Australia.
It’s normal for cities to be warmer than surrounding rural areas at night but researchers from the ARC Centre of Excellence for Climate Extremes at Monash University found heatwaves make this difference almost two and a half times greater under some heatwave conditions.
