UNSW-CAN2: Climate change and East African rainfall: combining observations from local farmers and weather stations

September 18, 2018 9:59 am Published by Comments Off on UNSW-CAN2: Climate change and East African rainfall: combining observations from local farmers and weather stations

Climate change is affecting weather patterns in many locations. In East Africa, changing rainfall would challenge the livelihoods of farmers. However, perceptions of local farmers and data from local weather stations differ. Is rainfall changing? How can we understand these two important information sources?

PhD opportunity: The attribution of heatwaves and compound events, UNSW Sydney

September 14, 2018 11:22 am Published by Comments Off on PhD opportunity: The attribution of heatwaves and compound events, UNSW Sydney

Heatwaves have increased in their intensity, frequency and duration. It is now well-established that heatwaves are not stand-alone events, but occur in the presence of other extremes, such as, droughts, extremely high atmospheric pressure, or teleconnections to other atmospheric phenomena. The PhD will undertake a novel examination of the attribution of heatwaves, coincident with other plausible extreme events.

Research brief: How well can climate models simulate interactions between cool and dry conditions under the current climate?

September 11, 2018 1:07 pm Published by Comments Off on Research brief: How well can climate models simulate interactions between cool and dry conditions under the current climate?

This paper shows that many models overestimate the interaction between hot and dry conditions in wet regions and therefore overamplify heat extremes. The study points to necessary model improvement to increase confidence in future projections of heat extremes.

Research brief: If dimethyl sulfide emissions ceased, Earth would warm 0.5C in a decade

August 15, 2018 12:12 pm Published by Comments Off on Research brief: If dimethyl sulfide emissions ceased, Earth would warm 0.5C in a decade

The study finds important regional consequences for precipitation and clouds formation if large changes in dimethyl-sulfide emissions were to occur.  In a hypothetical case where all marine DMS emissions cease completely, we find the Earth would warm by approximately 0.5 degrees C over a ten-year period.

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.

UNSW15: Does the frequency, intensity or duration of heatwaves and droughts affect how people vote in elections?

August 14, 2018 6:27 pm Published by Comments Off on UNSW15: Does the frequency, intensity or duration of heatwaves and droughts affect how people vote in elections?

Using France as a case study, this project aims to create a climatology of heatwaves and droughts to investigate possible connections with voting patterns. The ultimate goal would be to help predict voting patterns in the future and to see whether the techniques could be applied more widely to other countries.

UNSW14: Impacts of Southern Ocean warming on global sea-level rise

August 14, 2018 6:25 pm Published by Comments Off on UNSW14: Impacts of Southern Ocean warming on global sea-level rise

In this project the vacation scholar will use models, observations and theory to better understand the processes driving ocean heat uptake in the Southern Ocean, with particular applications to sea-level rise.

UNSW10: How will the Indian Ocean circulation change in a warming world?

August 14, 2018 5:59 pm Published by Comments Off on UNSW10: How will the Indian Ocean circulation change in a warming world?

This project will use output from a large ensemble of state-of-the-art climate models to examine changes to the Indian Ocean circulation and how it links to changes projected for the Pacific and Atlantic basins and surface winds.
