Research brief: Tasmanian marine heatwaves could be forecast years ahead
Marine heatwaves that impact southeast Australia could be forecast years in advance, with important implications for fisheries and the environment in this region

Research brief: Current Climate Models do not Project a More Persistent Central European Circulation
Central Europe has recently experienced extreme weather events, so researchers investigated whether this was the result of a weakening jet stream and changes to atmospheric circulation.

Research brief: CMIP6 models show some improvement over Australia
Australian researchers assess the ability of recently released climate models to simulate the climate of Australia and the new scenarios for 21st Century climate change.

Research brief: Why turbulence prevents models from replicating deep open-ocean convection
By comparing two models, CLEX researchers found that the current generation of convection parameterisations fail to replicate the random, chaotic nature of real-life turbulent convection.

Research brief: How the IOD Changes with global warming
All data sources agree that positive IOD events are becoming stronger and occur more often and that the mean-state of the Indian Ocean is moving towards a more positive IOD-like state due to enhanced warming in the west compared to the east.

Research brief: How warm water reaches Antarctica
Using a high-resolution ocean model, CLEX researchers unexpectedly found 80% of the transport in the warm water layer, known as Circumpolar Deep Water, approaches Antarctica in the colder regions.

Climate change and natural variability behind ocean warming anomaly
New study finds ocean heat asymmetry between hemispheres can be explained by natural variability in the climate system superimposed on long-term ocean warming.

Research brief: CMIP5 and CMIP6 Projections of Australia’s future climate compared
CLEX authors and colleagues from major Australian science organisations investigating climate examined the simulation of Australian climate in the new, state-of-the-art Coupled Model Intercomparison Project, phase 6 (CMIP6) models.

Research brief: SSTs create biases in how ENSO appears in CMIP5 models
A new study by CLEX researchers and colleagues shows that CMIP5 models as a group, when forced by observed sea surface temperatures underestimate, these atmospheric feedbacks on average by 23%. This underestimate can be linked to the wrong location at which climate models simulate the most important tropical circulation, called the Walker circulation.

Indian Ocean phenomenon spells climate trouble for Australia
New international research has found a worrying change in the Indian Ocean’s surface temperatures that puts southeast Australia on course for increasingly hot and dry conditions.

Research brief: Flexible definitions needed for fronts in Southern Ocean
This paper is a review article that stemmed from a debate within the Southern Ocean community. The paper explains how “fronts”, sharp boundaries between water masses, are defined, and what their effects might be on the biology of the Southern Ocean.
