Research brief: Winds impact upper ocean heat storage in Indian Ocean
Using ocean model simulations, this study demonstrates that the unusual behaviour of Indian Ocean temperatures over the past 60 years was mainly due to wind conditions.

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
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
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.

Research brief: New climate sensation scale can tell you how you feel
CLEX researchers and colleagues have developed a new six-dimensional semantic space to describe sensations and comfort outdoors.

Research brief: New roadmap aims to quickly integrate real-world data into ecosystem models
An international group of researchers performed a critical review of the information infrastructure that connects ecosystem modelling and measurement efforts. This group has now proposed a roadmap to community cyber-infrastructure development that can reduce the divisions between empirical research and modelling, accelerating the pace of discovery.

Research brief: The Sensitivity of Atmospheric River Identification
CLEX researchers explore the challenges of identifying atmospheric rivers and find that detecting these events is highly variable according to resolution, and choice of the integrated water vapour transport thresholds. The uncertainties in a single detection method and data parameters may be as large as uncertainties across AR detection methodologies.

Research brief: IPCC review reveals climate impacts occur at lower temperatures than previously thought.
An international review of IPCC reports since 2001 has found that as the science has improved with each report, a trend has appeared showing climate related impacts like heatwaves, the collapse of the West Antarctic ice sheet and coral bleaching are likely to occur at lower global mean temperatures than estimated in earlier reports.

Research brief: Tropical cyclones intensify more quickly in a warming world
CLEX researchers find rapidly intensifying hurricanes may become more frequent in a future warmer climate and the speed of this increase in intensity will continue to accelerate as the world’s oceans continue to warm.

Research brief: How uncertainties in data and drought indices affect drought identification
CLEX researchers examined the uncertainties of the input data of three commonly used drought indices, with the data coming from different sources, including observations and reanalysis. The ability of these indices to detect drought was assessed against soil moisture from multiple global land surface models.
