Research brief: Paris target impacts compared using pattern scaling projections and climate model outputs

July 13, 2018 6:48 am Published by Comments Off on Research brief: Paris target impacts compared using pattern scaling projections and climate model outputs

In relation to the Paris Agreement targets of 1.5°C and 2°C, new research shows the differences in results between pattern-scaling and climate model output were primarily due to forcings other than changes to greenhouse gas emissions.

Research brief: Regional climate models capture changes to extreme storms

July 12, 2018 6:46 am Published by Comments Off on Research brief: Regional climate models capture changes to extreme storms

Short, extreme rainfall events will increase in a warming climate, according to observations and climate models. Australian observations suggest these storms become smaller in size, with increased rainfall concentrating even more around the centre of the storm cell. However, there has been recent contradictory climate model research that suggests storm areas may become larger. To understand this contradiction the researchers compared two different model types to real world observations of storm cell changes that occurred with rising temperatures. An area... View Article

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.

Research brief: New insight into plant growth under climate change

July 6, 2018 3:43 am Published by Comments Off on Research brief: New insight into plant growth under climate change

The application of a simple carbon balance model, combined with a data assimilation approach, has the potential to improve the process understanding embedded in models, which is used to predict responses of the carbon cycle to climate change.

Research brief: Here’s what happens when you turn off convective parameterisations

July 6, 2018 2:42 am Published by Comments Off on Research brief: Here’s what happens when you turn off convective parameterisations

Convective parameterizations are widely believed to be essential for realistic simulations of the atmosphere, but are crude in today's weather and climate models. CLEX researchers, report on what happens when a number of these models are run with these schemes simply turned off.

Research brief: Droughts inconsistently represented across climate models

July 6, 2018 2:18 am Published by Comments Off on Research brief: Droughts inconsistently represented across climate models

This study evaluated GCMs for common drought metrics during the past 55 years. It found different models can produce very different simulations of drought, depending on the type of drought and metric analysed. The study points to a need to improve GCMs for droughts to reduce uncertainties in future projections.

Research brief: Tropical thunderstorms strengthen without cold pools

May 28, 2018 5:39 am Published by Comments Off on Research brief: Tropical thunderstorms strengthen without cold pools

In contrast to expectations, tropical thunderstorms without cold pools actually intensify, demonstrating unequivocally that cold pools can be detrimental to convection. Further investigations suggest that organised systems become maintained through atmospheric wave-convection interactions, which is a significantly different process to the established theory.
