Research brief: How salty seawater can tell us whether to expect rain

July 10, 2020 1:10 pm Published by Comments Off on Research brief: How salty seawater can tell us whether to expect rain

Ocean salinity could be an indicator of major rain events before IOD or ENSO events have peaked. This raises the prospect that long term forecasts for Australia could be improved by analysing sea surface salinity in the Indian and Pacific oceans.

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.

Mon02: Evaluate how the the IPO modulates precipitation extremes and drought risk across tropical continents

July 18, 2019 3:00 am Published by Comments Off on Mon02: Evaluate how the the IPO modulates precipitation extremes and drought risk across tropical continents

In this project, we will investigate the links between precipitation extremes and the Interdecadal Pacific Oscillation (IPO), including its signature in El Niño–Southern Oscillation (ENSO) impacts, across tropical land regions.

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.

Distant processes influence marine heatwaves around the world

An international team, led by Australian researchers from the ARC Centre of Excellence for Climate Extremes (CLEX) and the Institute for Marine and Antarctic (IMAS) studies, have published in Nature Communications the first global assessment of the major drivers of marine heatwaves.

Research brief: New statistical method identifies robust reconstructions of past ENSO events

May 13, 2019 2:19 pm Published by Comments Off on Research brief: New statistical method identifies robust reconstructions of past ENSO events

This study employs a new statistical approach to reconstructing ENSO which enables researchers to identify times in the past when palaeo-ENSO reconstructions are most robust. They found that ENSO reconstructions are most reliable from 1580-1700, and from 1825 to present.
