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: Sunny days power shallow Marine heatwaves

September 9, 2021 12:41 pm Published by Comments Off on Research brief: Sunny days power shallow Marine heatwaves

Coral bleaching events have been reported over the Great Barrier Reef during La Niña events and the neutral phase of the El Niño–Southern Oscillation, when large-scale sea-surface temperatures may be cooler than normal. How does this occur?

Research brief: How ENSO affects the North Atlantic

July 14, 2021 1:23 pm Published by Comments Off on Research brief: How ENSO affects the North Atlantic

In this study, CLEX researchers and colleagues showed that the North Atlantic sea-surface temperature response to ENSO is nonlinear with respect to the strength of the sea-surface temperature forcing in the tropical Pacific.

Research brief: Warmer oceans amplify LENGTH AND FREQUENCY of coastal marine heatwaves

March 5, 2021 1:19 pm Published by Comments Off on Research brief: Warmer oceans amplify LENGTH AND FREQUENCY of coastal marine heatwaves

CLEX researchers found coastal marine heatwave hotspots were concentrated along the Mediterranean Sea, Japan Sea, south‐eastern Australia and the north‐eastern coast of the United States. They also found the frequency of these events and their duration globally increased by 1–2 events per decade and 5–20 days per decade. Most of the marine heatwave hotspots identified were associated with high upward trends.

Research Brief: SST adjustments radically alter projections of tropical cyclones in a warming world

April 15, 2020 3:18 pm Published by Comments Off on Research Brief: SST adjustments radically alter projections of tropical cyclones in a warming world

Most climate models correct for current SSTs but don't correct for the reliability of future SSTs. This study shows that making that additional correction has a profound impact on how tropical cyclones will develop in a warmer world.

Research brief: SSTs create biases in how ENSO appears in CMIP5 models

March 13, 2020 9:49 am Published by Comments Off on Research brief: SSTs create biases in how ENSO appears in CMIP5 models

A new study by CLEX researchers and colleagues shows that CMIP5 models as a group, when forced by observed sea surface temperatures underestimate, these atmospheric feedbacks on average by 23%. This underestimate can be linked to the wrong location at which climate models simulate the most important tropical circulation, called the Walker circulation.

Research brief: Statistical correction reveals 25% decline in future rainfall over the SW Pacific

April 29, 2019 2:19 pm Published by Comments Off on Research brief: Statistical correction reveals 25% decline in future rainfall over the SW Pacific

CLEX researchers found that applying a statistical correction to projected sea surface temperatures has a major impact on changes to rainfall with global warming, leading to a 25% reduction in future precipitation projected for the south-western Pacific.

MON3: Impact of tropical sea surface temperatures on climate extremes in Australia

August 14, 2018 3:32 pm Published by Comments Off on MON3: Impact of tropical sea surface temperatures on climate extremes in Australia

The aim of this project is to gain a better understanding of the drivers of seasonal climate extremes over Australia, with a focus on the potential role of tropical ocean basins. The student researcher will use a range of observations and climate model outputs to examine the variability of extreme temperature and rainfall across Australia.
