Research brief: Lost and found? A search for the Tasman Front
Gabriela Pilo and colleagues find that the Tasman Front is not so much a constant current, as is widely accepted, but switches between being an extension of the East Australian Current and an eddy field.

Research brief: More accurate prediction of tree mortality during droughts
CLEX researchers working with colleagues from the Hawkesbury Institute for the Environment revealed a method to predict the probability of tree mortality during droughts.

Research brief: New calculations reveal Arctic could be ice-free at 1.5°C
Climate scientists testing a new mathematical and statistical method that converts projections of future climate outcomes in a warming world into reliable probabilities have found there is a significant chance the Arctic could be ice-free even if world leaders meet the Paris targets of 1.5°C and 2°C.

Research brief: New dataset shows NW cloudbands are increasing over Australia
The 21st Century has seen an increase in northwest cloudbands across Australia, according to a new dataset developed by CLEX researchers.

Research brief: Winter storms accelerate disintegration of sea ice in the Arctic
Winter storms over the Arctic leave a legacy that breaks up the ice, melts it from beneath and has led to constant ongoing decline in old ice that far exceeds the period of the storm itself.

Research brief: Indian Ocean played key role in rapid 2016 Antarctic ice decline
Antarctic sea ice had been growing in area since 1979, despite the influence of global warming. Then unexpectedly in the austral spring of 2016, there was a rapid decline. CLEX researchers used multiple runs of a coupled ocean-atmosphere climate model to investigate whether these distant influences played a role and, if so, the level of the contribution to the sea-ice decline.

Research brief: Is the pattern of Earth’s warming going to change and why?
New study highlights local warming is expected to accelerate beyond the global average in mid latitude regions, especially in summer. Over oceans the rise will be below global average warming.

Research brief: Tropical atmosphere’s balancing act breaks down at regional levels
This observational study of radiative convective equilibrium finds that this equilibrium breaks down in areas of a few thousands kilometres on a side. This has implications cloud model simulations in climate models.

Research brief: New downscaling approach will help urban planners prepare for future rainfall
CLEX researchers and colleagues have developed a downscaling methodology using the HiDRUS model that accurately projects future rainfall in 1km grids at six minute intervals. This will be a boon for urban planners who need to build infrastructure to cope with the different future heavy rainfall events that will occur in a changing climate.

Research brief: Nutrient availability framework accurately forecasts plant growth from CO2 fertilisation effect
CLEX researchers and colleagues revisit the quasi-equilibrium analytical framework introduced by Comins and McMurtrie (1993) and explore the consequences of specific model assumptions for ecosystem net primary productivity (NPP).

Research brief: Observations of small ocean eddies in the Arctic using glider technology
Using novel ocean glider technology, a team of researchers from France, Norway, and Australia observed small eddy-like lenses of cold water in July 2017 along the western Svalbard shelf in the Arctic.

Research brief: Towards reliable extreme weather and climate event attribution
New work published in Nature Communications develops a correction method that ensures the probability of climate extremes in the model simulations are consistent with real-world observations. In addition, it also corrects the rate of the long-term changes and the inter-annual variability so that it is consistent with observations.
