How climate change impacts prescribed burning days
Climate change will affect prescribed burning days in the future. Unexpectedly, it is not all bad news, but as the coming century progresses there are definitely changes ahead for our firefighters in Australia when it comes to preparing for a fire season, especially along the east coast of Australia.

Need for prediction of marine heatwaves
CLEX researchers and colleagues have highlighted the need for the development of systems to predict marine heatwaves, which are a growing threat to marine ecosystems and industries as the climate changes.

Research brief: Decomposing temperature extremes errors in CMIP5 and CMIP6 models
CLEX researchers addressed the error compensation issue for temperature extremes by defining a novel performance metric that identifies those models that can simulate temperature extremes well and simulate them well for the right reasons.

Marine heatwaves affecting the ocean’s tiniest organisms
Tiny microbes at the base of the ocean food chain will be increasingly affected by marine heatwaves as the climate changes.

Heatwave trends accelerate worldwide
The first comprehensive worldwide assessment of heatwaves down to regional levels has revealed that in nearly every part of the world heatwaves have been increasing in frequency and duration since the 1950’s. The research has also produced a new metric, cumulative heat, which reveals exactly how much heat is packed into individual heatwaves and heatwave seasons.

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

Historical records reveal new trends in Australian temperatures
CLEX researchers have developed Australia’s longest daily temperature record, identifying a decrease in cold extremes and an increase in heatwaves around Adelaide since 1838.

Research brief: Realised added value in dynamical downscaling of Australian climate change
New research shows regional climate models consistently provide added value across Australia compared to global climate models. As a result, researchers and policymakers can obtain plausible improvements in future climate projections from the current generation of available RCMs.

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: First observational analysis of SSW events shows winter impacts.
When the “Beast from the East” brought cold temperatures and heavy snowfall to western Europe in February and March 2018, a lot of people were quick to link the extreme weather to a sudden stratospheric warming (SSW) that had recently occurred. CLEX researchers found there was a surprising lack of research on the relationship between SSWs and climate extremes in Europe using observations, so they sought to look at this in more detail to see if this link can really be made.

Research brief: How land and ocean characteristics impact wintertime stationary waves.
This study looks at the average climate in the northern hemisphere with a simplified climate model. It considers the atmospheric effects of mountain ranges (Tibet, Rockies), contrasts between land and ocean surface, and ocean currents at the surface (such as the Gulf Stream) and their impact on winter climate.

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.
