Briefing note 17: Could understanding the Indian Ocean improve climate predictions for Australia?

You may have heard about the influence of sea surface temperatures (SSTs) in the tropical Pacific Ocean on Australia’s climate and how forecasts of the El Niño–Southern Oscillation (ENSO) help to give warnings of flood, drought and bushfire risk in Australia months in advance… but what about the tropical Indian Ocean?

Research brief: How El Niños impact climate in the southwest Indian OCean

March 9, 2021 3:13 pm Published by Comments Off on Research brief: How El Niños impact climate in the southwest Indian OCean

El Niño effects are communicated to the Indian Ocean via both large‐scale atmospheric circulation changes over the southern tropical ocean basin and via disturbances to sea‐levels along the coast of Western Australia. CLEX researchers investigated these remote ENSO influences in a state‐of‐the‐art climate model.

RP4 Teleconnections & Variability Report – December 2020

It has been remarkable how much we have achieved in this extraordinarily difficult year. Research coming out of the Teleconnections and Variability program over the past four months has strongly focused on how influences in one part of the world can have direct impacts on another.

Research brief: Indian Ocean warming modulates global atmospheric circulation trends

November 27, 2020 3:25 pm Published by Comments Off on Research brief: Indian Ocean warming modulates global atmospheric circulation trends

Using atmospheric model experiments, researchers have shown that the warming of the tropical Indian Ocean relative to the other two tropical ocean basins can effectively control Walker Circulation changes in the Pacific and Atlantic oceans and influence climate far beyond the Indian Ocean region.

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: How the IOD Changes with global warming

May 5, 2020 9:17 am Published by Comments Off on Research brief: How the IOD Changes with global warming

All data sources agree that positive IOD events are becoming stronger and occur more often and that the mean-state of the Indian Ocean is moving towards a more positive IOD-like state due to enhanced warming in the west compared to the east.
