Category: RP2 Heatwaves and cold outbreaks
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.Read More
CLEX researchers have developed Australia’s longest daily temperature record, identifying a decrease in cold extremes and an increase in heatwaves since 1838. Lead researcher Dr Joelle Gergis a lead Associate Investigator from The Australian National University (ANU) says the study examined daily records from around Adelaide.Read More
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.Read More
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.Read More
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.Read More
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.Read More
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.Read More
Using a simplified climate model, researchers forced the south polar winds to reverse arbitrarily and found that the final impact at the surface is indistinguishable from events where the winds reverse in response to natural phenomena.Read More
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.Read More
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.Read More
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.Read More
In this work, CLEX researchers compared the performance of three ocean simulations – with low, medium and high resolutions – when representing marine heatwaves.Read More
