Research brief: Measuring spread in spatio-temporal changes of ocean heat content estimates

November 24, 2021 12:09 pm Published by Comments Off on Research brief: Measuring spread in spatio-temporal changes of ocean heat content estimates

90% of the heat trapped on Earth by anthropogenic greenhouse gasses is absorbed by the ocean, with the unfortunate by-product of thermosteric sea level rise - as the ocean warms, it expands. Therefore, it is essential that we can accurately measure how much heat the ocean is absorbing over time.

ANU01: Southern Hemisphere atmospheric circulation

July 19, 2021 1:35 pm Published by Comments Off on ANU01: Southern Hemisphere atmospheric circulation

Anthropogenic climate change has been most clearly observed in the world's midlatitude regions. The limited number of observations for the Southern Hemisphere has prevented the development of a long-term understanding of these changes. This project aims to fill this critical gap by examining daily changes in Southern Hemisphere atmospheric circulation back to 1830. To do this, the project will build on recently recovered daily instrumental weather observations for southern Australia.

MON02: THE ANTARCTIC OZONE HOLE AND AUSTRALIAN RAINFALL

August 6, 2020 3:47 pm Published by Comments Off on MON02: THE ANTARCTIC OZONE HOLE AND AUSTRALIAN RAINFALL

In this project you will investigate the competing effects the Antarctic ozone hole and increasing greenhouse gases have on the Australian summer season rainfall, using the latest climate models. These are now available on the National Computing Infrastructure (NCI) supercomputer and are being used as input into the Intergovernmental Panel on Climate Change’s Sixth Assessment Report.

CSIRO03: Exploring the dynamics of decadal variability and transitions in climate teleconnections

August 6, 2020 1:47 pm Published by Comments Off on CSIRO03: Exploring the dynamics of decadal variability and transitions in climate teleconnections

This project will focus on the connection between conceptual climate models and high resolution general circulation models (GCMs). The student will analyse simplified models that represent teleconnection behaviour and calibrate them to reflect the settings of a GCM. The student will also have access to high dimensional GCM output and can compare an ensemble of “real-world” simulations to the behaviour of the conceptual model using statistical methods.

ANU01: Are recent climate extremes really ‘extreme’?

July 15, 2019 1:00 am Published by Comments Off on ANU01: Are recent climate extremes really ‘extreme’?

This project will use output from state-of-the-art climate simulations of the Last Millennium (850–2005 CE) to explore the long-term variability of an Australian climate driver of the student’s choice. The student will explore the natural variability of that driver to determine its long-term context, and compare with palaeoclimate reconstructions (proxies) where possible.
