Recent studies have debated whether the two types of sudden stratospheric warming – displacement events when the vortex is displaced off the Pole and split events when the vortex splits into two smaller vortices – have differing near-surface impacts.
CLEX researchers have constructed the oldest daily historical climate dataset for Perth, southwestern Australia, to provide an extended record for analysing pre‐industrial climate variability and extremes for the region.
An international team of researchers performed a systematic evaluation of simulations made by nine FireMIP models in order to quantify their ability to reproduce a range of fire and vegetation benchmarks.
Different expressions of El Niño do affect interannual variability in the terrestrial carbon cycle. However, the effect over longer timescales is small. This means the changing frequency of these two types of El Niño events may be of little importance in terms of robustly simulating the future terrestrial carbon cycle.
The discovery of changing eddy energy was made by a team of ANU and UNSW researchers from the ARC Centre of Excellence for Climate Extremes. Their work, published today in Nature Climate Change, shows clear changes to the distribution and strength of these eddies, which had not been previously detected.
Welcome to all of our new students. We have held two inductions since our last newsletter and in both we had more than 20 new students dial in. Many of you are still offshore, however we are starting to hear of success stories when it comes to travel exemptions for international students.
Andrew King recently presented his research into the seasonal prediction of extreme rainfall to an audience of federal government, state government, and agricultural industry stakeholders as part of the Forewarned is Forearmed Community of Practice (FWFA CoP).
With the recategorisation of our research programs, modelling research has now become a program of its own even though it underpins and works with every other research program. A key focus of this program is the development of Australia’s ACCESS model.
CLEX’s world-leading research in Oceans Extremes, particularly around marine heatwaves, explains why this research program has come into being as a standalone area of investigation amidst the rearrangement of the CLEX research programs.
Understanding what causes droughts and what brings about their conclusion is key work in a dry continent like Australia. Often, we use computer models and modern observations to reach our conclusions but sometimes the clues to these questions can be uncovered in the past.
