This study highlights the importance of simulating global and regional warming responses correctly, to enable more accurate estimates of how the occurrence probability of climate extremes may change in a warming climate.
New research clearly demonstrates the potential to predict long-term LAI using simple ecohydrological theory. This approach could potentially be incorporated into existing terrestrial biosphere models and help improve predictions of LAI.
Over four years, the Norwegian Polar Institute’s (NPI) Ocean and Sea Ice team used the social media handle @oceanseaicenpi across Instagram, Twitter and Facebook to communicate its research to peers and the public.
Research brief: Paris target impacts compared using pattern scaling projections and climate model outputsJuly 13, 2018 6:48 am 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.
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
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.
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.
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.
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.
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.
