In this work CLEX researchers aim to understand a few popular ways to parameterize convection. They extracted one vertical column from five different GCMs and lightly tickled (perturbed) it and then observed the responses.
Project Coolbit, is an ongoing investigation that aims to create a personalised approach to assessing thermal comfort and preventing health complications during extreme heat events. It is research that could not only save the lives of individuals but may also change the way we design future cities.
Lee Constable interviews Prof Christian Jakob about what we don't know about climate change for her channel on the Cimpatico Studios platform, Climate Australia.
This study is based the well-established fact that sea ice cover is very closely related to surface air temperature, so that we can use trends in Antarctic sea ice as an independent validation for the reanalysis trends.
In this paper, the researchers investigated how a major glacier tongue break in the Mertz polynya in Antarctica impacted phytoplankton blooms. Larger phytoplankton blooms increase the amount of carbon that can be stored in the deep ocean.
By grouping weather systems by similar patterns rather than averaging conditions over months, seasons or years, CLEX researchers found that between Australia and Antarctica, the ‘doughnut’ structure of SAM is split into multiple ‘flavours’ and is more likely to have ‘bite marks’ out of it than be a perfect ring.
Research brief: New protocol aims to improve the quality and communication of extreme event attributionNovember 23, 2020 3:32 pm Comments Off on Research brief: New protocol aims to improve the quality and communication of extreme event attribution
This paper aims to catalogue the steps the authors have found make up a successful framework for event attribution analyses. The hope is that this paper will be useful for those considering how to undertake such work themselves and to highlight some of the potential issues and pitfalls that can arise along the way.
Using ocean model simulations, this study demonstrates that the unusual behaviour of Indian Ocean temperatures over the past 60 years was mainly due to wind conditions.
A landmark new international review of climate sensitivity led by ARC Centre of Excellence for Climate Extremes researcher Prof Steven Sherwood has reduced the uncertainty in Equilibrium Climate Sensitivity. Estimates of likely values now vary by less than a factor of two. The new assessment concludes that the climate is more sensitive to atmospheric carbon dioxide than some previous estimates.
In a new study published in Nature Scientific Reports, a group of oceanographers, atmospheric scientists, ecologists and fisheries experts got together to identify the most severe marine heatwaves over recent decades. The objective was to understand what triggered these events and led to their ultimate demise.
