Yue Li
PhD student
(supervisors: Alex Sen Gupta, Andrea Taschetto, Nico Jourdain)
Yue is using a regional coupled climate model to understand the factors affecting the dramatic diurnal cycle in rainfall over the Maritime Continent

Nicola Maher

PhD student (supervisors: Matt England, Alex Sen Gupta)
Nicola is interested in the subduction of heat into the ocean. Her research will focus on how the ocean heat content is affected by the additional input of energy into the Earth’s system due to climate change.

Dipayan Choudhury

PhD student (supervisors: Ashish Sharma, Alex Sen Gupta, Raj Mehrotra, Sivakumar Bellie)
Dipayan is using decadal climate forecast from the CMIP5 archive to understand the predictabilty of hydrographic conditions over Australia

 

 

Yue Li (Masters Research Project & Masters by research) 2010; 2011-2012

Yue examined ocean-atmosphere interactions and their role in monsoon variability.  In particular, she looked at the mechanisms controlling the Asian-Australian monsoon system, the Tropospheric Biennial Oscillation (TBO), and their relationship with the Indian and Pacific SST variability in observations and climate models

Yue spent a semester in 2010 looking at how well different datasets represent Indian Monsoon rainfall and how the Monsoon is affected by large scale modes of variability (in particular ENSO and IOD).

Yu-Heng (ian) Ting (Research Internship) 2010

Ian thesis: "Response of the Australian Climate System to Variations in the Southern Annular Mode" examined how the SAM influences rainfall over regions of Australia.

Giovanni Di Virgilio (Masters Research Project) 2009

Giovanni made a detailed analysis of a 60-year oceanographic record from Port Hacking, NSW. He found robust long-term warming in the region. He also examined low frequency variability in the signal and how it related to slow variations in the circulation of the sub-tropical gyre and ultimately changes in large-scale wind patterns.

CLIMATE CHANGE & FISHERIES

Pacific Islanders are heavily reliant on the oceans bounty for food security, livelihoods and economic growth. Over the next 25 years the population of the tropical Pacific is set to rise by 50%. This will put enormous strain on marine resources. At the same time Global Warming will significantly modify the ocean environment that supports vital fisheries and aquaculture.
In this project we examine the the Tropical Pacific might change in the future and how this will affect marine species.

CLIMATE CHANGE IN THE TROPICAL PACIFIC

The climate of tropical Pacific Island is dominated by the ocean. Changes to the ocean will therefore have major implications for the region. A collaboration between BOM, CSIRO, Australian Universities and Island stakeholders, under the banner of the PCCSP, are putting together a major new analysis of Climate Change in the Pacific.

OCEANS DRIVING AUSTRALIAN RAINFALL

Subtle changes to ocean temperature can control regional rainfall patterns, as dramatically demonstrated by the the La Nina induced Queensland floods. We have shown that changes in the Indian Ocean are often as important as those in the Pacific Ocean (associated with ENSO) for rainfall changes in western and eastern Australia and in other Indian Ocean rim countries.
In particular Indian Ocean variability is strongly implicated in causing the worst historical droughts over southeastern Australia

MONSOON AND MODOKI

In recent years the signature of El Ninos seems to have changed, Instead of causing broad scale warming in the eastern Pacific El Ninos now often produce warming confined to the central Pacific - these are termed El Nino Modoki. Our work has shown that during Modoki events the Australian monsoon doesn't follow its normal progression - instead it starts late, terminates early and becomes more intense

Recent work also shows that the Indian monsoon that is normally extra strong during El Nino years can be weakened by the Indian Ocean Dipole

OYSTERS & CARBON SEQUESTRATION

Carbon credits wil be a lucrative extra income to some businesses in the future. But does growing oysters remove carbon from the atmosphere as some have claims?

Ocean chemistry means that the growth of oyster shell actually increases dissolved CO2 concentration and so slows the sequestration of CO2 from the atmosphere (read more)
