Research Brief: Regional variations in projections of recent changes in the western boundary currents

November 24, 2021 12:44 pm Published by Comments Off on Research Brief: Regional variations in projections of recent changes in the western boundary currents

Strong ocean currents are found on the western side of the ocean basins, which flow from the tropics toward the poles in both hemispheres. These western boundary currents have shown strong changes in the last few decades, resulting in intensified ocean warming and are projected to amplify further in the future.

Briefing note 14: The latest global climate models present challenges for generating climate projections

Climate sensitivity describes how sensitive the Earth’s temperature is to a doubling of the amount of carbon dioxide in the atmosphere. One measure of climate sensitivity for projections of future climate is the Equilibrium Climate Sensitivity (ECS). ECS is the increase in the global average temperature between the pre-industrial era and a future doubled carbon dioxide climate once equilibrium of the climate has been reached.

Changing ocean eddies reorganise ocean energy

April 23, 2021 1:01 am Published by Comments Off on Changing ocean eddies reorganise ocean energy

The discovery of changing eddy energy was made by a team of ANU and UNSW researchers from the ARC Centre of Excellence for Climate Extremes. Their work, published today in Nature Climate Change, shows clear changes to the distribution and strength of these eddies, which had not been previously detected.

Research brief: Extreme events in SE Australia to increase in frequency by 2100

March 25, 2021 12:01 pm Published by Comments Off on Research brief: Extreme events in SE Australia to increase in frequency by 2100

This paper used statistical techniques to investigate changes in extreme climate events that currently occur, on average, only once every 20 years. These techniques are applied to data related to heat, rainfall, drought and conditions conducive to bushfires and thunderstorms from detailed climate modelling commissioned by NSW and ACT Governments.

Research brief: The interaction of ocean basins may improve long-term climate predictions

December 17, 2020 10:58 am Published by Comments Off on Research brief: The interaction of ocean basins may improve long-term climate predictions

An international team of authors led by NCAR scientist and CLEX PI Jerry Meehl, along with CLEX CIs and AIs, propose that the Pacific and Atlantic ocean basins are mutually interactive, with each basin influencing and responding to processes in the other basin.

CSIRO02: Analysing long tide gauge records in Australia in conjunction with the 20th Century reanalysis to better understand how extreme events and by association extreme sea level events are changing

August 6, 2020 1:46 pm Published by Comments Off on CSIRO02: Analysing long tide gauge records in Australia in conjunction with the 20th Century reanalysis to better understand how extreme events and by association extreme sea level events are changing

Understanding historical changes in extreme sea levels is necessary for the accurate projection of their changes over the next century. This project will look at digitized sea level data, to better understand the causes of extreme sea levels the southern Australian region and how these events vary over the duration of the record.
