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.

Research brief: More hot days at the same global temperature in a warming world than a world where warming has plateaued.
Using a novel methodology applied to CMIP5 projections CLEX researchers found that the local temperatures experienced by 90% of people would be substantially higher in a transient (still warming) climate than an equilibrium climate where the temperatures have plateaued, for the same global temperature.

Research brief: Satellite estimations may overcome data-sharing issues for precipitation
This study looks at data-sharing issues and outlines the history of the rationale and use of indices, the types of indices that are frequently used and the advantages and pitfalls in analysing them.

Research brief: SAM may be unrelated to mid-latitude weather.
Research by CLEX scientists and colleagues re-examines some of the basic assumptions and interpretations in the theory. In particular, they show the SAM cannot be interpreted as a descriptor of mid-latitude variability and it has little imprint on the weather of the storm track.

Research brief: Algorithm improvements reduce errors in ocean chlorophyll observations
CLEX researchers evaluate the performance of satellite chlorophyll observations in the tropical Pacific Ocean and suggest algorithm improvements.

Research brief: New model shows how air conditioners will change energy demand with climate change
This work describes a new cross-scale modelling framework for urban environments and applies it to calculate how electricity and gas demand will change under future climate change and air conditioner (AC) ownership scenarios.

Research brief: Marine heatwaves – the models vs reality
In this work, CLEX researchers compared the performance of three ocean simulations – with low, medium and high resolutions – when representing marine heatwaves.

Research brief: Analysis of CABLE model in a WRF physics ensemble over Australia
CLEX researchers evaluated an updated version of CABLE climate model within a WRF physics ensemble over the CORDEX AustralAsia domain. Results were strongly dependent on the region of interest.

Research brief: How dry soils amplify Australian heatwaves
CLEX researchers found that regions where there is a larger drying trend tend to be more sensitive to land water availability and have more heatwave days. They found that the effect of dry soils before a heatwave varies considerably across Australia.

Research brief: Climate change to slow Indian Ocean circulation
Climate models project that all circulation features of the South Indian Ocean, including the Leeuwin Current and Undercurrent, North and South East Madagascar Currents, transport through the Mozambique Channel and Agulhas Current are projected to weaken significantly in the last half of the 21st century with unchecked greenhouse gas emissions.
