Research brief: How dryness affects plant hydraulics in different systems

November 24, 2020 12:27 pm Published by Comments Off on Research brief: How dryness affects plant hydraulics in different systems

In this paper, the researchers investigated how dryness, represented by the aridity index, affects the inter-annual variability of ecosystem iso/anisohydricity at the regional scale, estimated using satellite microwave vegetation optical depth observations.

Research brief: Hemispheric index fails to capture Variations in winds around Antarctica

November 24, 2020 12:09 pm Published by Comments Off on Research brief: Hemispheric index fails to capture Variations in winds around Antarctica

By grouping weather systems by similar patterns rather than averaging conditions over months, seasons or years, CLEX researchers found that between Australia and Antarctica, the ‘doughnut’ structure of SAM is split into multiple ‘flavours’ and is more likely to have ‘bite marks’ out of it than be a perfect ring.

Research brief: Uncertainty of future wheat yield varies with location

November 23, 2020 3:56 pm Published by Comments Off on Research brief: Uncertainty of future wheat yield varies with location

CLEX researchers and colleagues examined the contribution to uncertainty in simulated future changes in crop yields using the change-factor method and an additional, more sophisticated, statistical downscaling method of generating realistic future climate data from climate model output.

Research brief: New protocol aims to improve the quality and communication of extreme event attribution

November 23, 2020 3:32 pm Published by Comments Off on Research brief: New protocol aims to improve the quality and communication of extreme event attribution

This paper aims to catalogue the steps the authors have found make up a successful framework for event attribution analyses. The hope is that this paper will be useful for those considering how to undertake such work themselves and to highlight some of the potential issues and pitfalls that can arise along the way.

Record Breakers: What causes the longest, largest and most intense ocean heatwaves

November 17, 2020 11:31 am Published by Comments Off on Record Breakers: What causes the longest, largest and most intense ocean heatwaves

In a new study published in Nature Scientific Reports, a group of oceanographers, atmospheric scientists, ecologists and fisheries experts got together to identify the most severe marine heatwaves over recent decades. The objective was to understand what triggered these events and led to their ultimate demise.

Research brief: tropics and SOUTHERN HEMISPHERE subtropics were drier in the mid‑Pliocene Warm Period

November 2, 2020 2:28 pm Published by Comments Off on Research brief: tropics and SOUTHERN HEMISPHERE subtropics were drier in the mid‑Pliocene Warm Period

New study shows November-to-March precipitation (when rainy season peaks over most of the Southern Hemisphere land mass) was significantly reduced both in the Southern Hemisphere tropics and subtropics due to a weakening of the subtropical convergence zones during the mid-Pliocene Warm Period.

Research brief: Tropical rainfall modelling errors decrease slowly, but storm resolving models may be the future

October 23, 2020 10:24 am Published by Comments Off on Research brief: Tropical rainfall modelling errors decrease slowly, but storm resolving models may be the future

An international team including CLEX researchers examined models used by the Intergovernmental Panel for Climate Change (IPCC) over three model phases linked to IPCC reports – CMIP3, CMIP5, and the most recent, CMIP6, to see if they improved representation of tropical rainfall.
