RP3 Drought report – August 2020

August 17, 2020 1:34 pm Published by Comments Off on RP3 Drought report – August 2020

The Drought program farewells Michael Roderick who has retired and looks over an extensive range of research that has been carried out despite the global pandemic. Some significant model improvements, new datasets and deeper insights into past and future climates show the depth of the research effort.

Research brief: How to incorporate increased vapour pressure deficit into climate models

October 25, 2019 12:23 pm Published by Comments Off on Research brief: How to incorporate increased vapour pressure deficit into climate models

With projected increases in temperature in the future, the amount of water vapour that can be held at saturation – before it condenses into clouds, dew or water film – increases exponentially. As this deficit increases plants tend to close their stomata, which reduces water fluxes into the boundary layer. Do models currently capture the observed leaf-level response to increasing vapour pressure deficit? What about at very high levels of this deficit?

Research brief: Drought not an automatic result of climate change

December 18, 2018 11:26 am Published by Comments Off on Research brief: Drought not an automatic result of climate change

New research in Nature Climate Change suggests droughts may not increase as a result of climate change. This finding resulted from researchers investigating an apparent climate model contradiction that saw climate change projections of the 21st Century produce increased droughts along with more run-off and a greening of the landscape

RP4 Climate variability and teleconnections report: December 18

It has been a very active time for the Climate Variability and Teleconnections Research Program in terms of research and engagement activities right across the team, including two expeditions - one drilling coral cores in the tropics and another going south to the Antarctic Circumpolar Current.

RP3 Drought report: December 2018

The Drought program has been strongly focused on evaluating and improving climate models, and developing a drought database for documenting drought and for benchmarking model performance.

Research brief: Southern Ocean’s clockwise eddies are most productive

August 15, 2018 10:43 am Published by Comments Off on Research brief: Southern Ocean’s clockwise eddies are most productive

CLEX researchers found that counter-clockwise rotating eddies in the Southern Ocean mix the ocean deeper in winter, allowing more nutrients to enter their interiors, leading to higher productivity.  This work is important because eddy productivity plays a significant role in the exchange of carbon between the ocean and the atmosphere.

Research brief: Some trees may survive future heat better than expected

July 11, 2018 11:53 pm Published by Comments Off on Research brief: Some trees may survive future heat better than expected

This research suggests some trees and in particular, Australian trees, may be more resilient than expected to future warming and extreme events. These findings have implications for planning around which species to plant in “green cities” to help mitigate future climate extremes.
