Research brief: Tickling climate models reveals their bad behaviour

March 22, 2021 3:35 pm Published by Comments Off on Research brief: Tickling climate models reveals their bad behaviour

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.

How a watch could save your life on a hot day

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.

Research brief: Hemispheric index fails to capture Variations in winds around Antarctica

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 attribution

November 23, 2020 3:32 pm Published by 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.

Briefing note 12: How sensitive is the Earth’s temperature to the amount of carbon dioxide in the atmosphere?

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.

Record Breakers: What causes the longest, largest and most intense ocean heatwaves

November 17, 2020 11:31 am Published by Comments Off on Record Breakers: What causes the longest, largest and most intense ocean heatwaves

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.
