AMOS award nominaitons
A reminder that AMOS Uwe Radok Award entries (for best PhD thesis) are due at the end of May. Find out more here.
AAS: The Science of climate change Q&A
Chief investigators Steve Sherwood and Matthew England played key roles in the updated version of the Australian Academy of Science's booklet, The Science of Climate Change: Questions and Answers. The 2015 booklet updates the first edition, which was released in 2010. You can find the booklet here.
Nicola Maher was shown the following tools when she recently visited NCAR. These are free to use and may be helpful to some of you who use CMIP5 models or various observational datasets.
- Climate variability indices: This link will give you the opportunity to look at plots or download data for various climate indices calculated for all CMIP5 models and CESM ensembles.
- Observational datasets: This link gives information on different datasets for many variables to help to decide which dataset is most useful for your needs. It includes the strengths and weaknesses of each dataset.
Dr Nerilie Abram receives the 2015 Dorothy Hill Award
Congratulations to Centre associate investigator Dr Nerilie Abram who was recently named by the Australian Academy of Science as the recipient of the 2015 Dorothy Hill award. The award supports research in the Earth sciences, by female researchers up to 10 years post PhD. The Academy said Dr Abram won the award for her "pioneering research addresses the past behaviour of the Earth's climate system, and implications for anthropogenic climate change. Her outstanding research portfolio has generated unique new records of past climate and environmental impacts from regions spanning the tropics to Antarctica, and assessing these alongside state-of-the-art climate models. Her high-impact work has led to groundbreaking advances in understanding how climate change is impacting Southern Ocean winds, Antarctic temperatures, and Australian rainfall patterns."
Congratulations to Prof David Karoly and Dr Sophie Lewis, who have both been recognised with awards from AMOS for their outstanding work. Read more.

Clouds, circulation and climate sensitivity (Nature Geoscience)
This paper by a large group of authors led by Sandrine Bony with our own Christian Jakob and Steve Sherwood explores the four key questions that need to be focused on to improve our understanding of clouds, circulation and climate interactions. They involve understanding the role of cloud feedbacks and convective organization in climate, and the factors that control the position, the strength and the variability of the tropical rain belts and the extratropical storm tracks.
Increases in tropical rainfall driven by changes in frequency of organized deep convection (Nature)
Jackson Tan’s PhD resulted in this paper that finds increases in tropical convection have been caused by the increased number of large storms, yet the total number of storms has not changed. There is some suggestion that the dynamics of the atmosphere in tropical regions may have changed for this to occur. You can ask co-author Christian Jakob about this.
Recent reversal in loss of global terrestrial biomass (Nature Climate Change)
Yi Liu and colleagues used satellite measurements to show that through recent greening of savannah landscapes and changes in land use we have seen the vegetation equivalent of a 4 billion tonne increase in carbon. However, this is a fragile increase that seems primarily weather dependent.
Recent trends in Southern Ocean eddy field (Journal of Geophysical Research)
Intensifying wind over the Southern Ocean has increased the speed and energy of eddies and jets, which are responsible in large part for the movement of nutrients, heat and salt across the ocean basin. The increased movement and overturning of these eddies and jets has accelerated the carbon cycle and driven more heat into the deep ocean.
Antarctic contribution to meltwater pulse 1A from reduced Southern Ocean overturning (Nature Communications)
Around 14,000 years ago a large pulse led to a sea level rise of 3-4m. This research suggests this was caused by stratification of waters around Antarctica with a warm layer below a colder layer. These conditions are very similar to changes we are currently seeing around Antarctica.
