A group of international researchers using CMIP6 models to determine how heavy precipitation events will alter with climate change. The northern hemisphere in particular showed a strong warming signal for increased precipitation.
Focusing on the land regions around the world, the researchers assessed the representation of annual maximum of daily precipitation (Rx1day) across 22 observational products gridded at 1°x1° resolution.
An international team, led by Australian researchers from the ARC Centre of Excellence for Climate Extremes (CLEX) and the Institute for Marine and Antarctic (IMAS) studies, have published in Nature Communications the first global assessment of the major drivers of marine heatwaves.
New work published in Nature Communications develops a correction method that ensures the probability of climate extremes in the model simulations are consistent with real-world observations. In addition, it also corrects the rate of the long-term changes and the inter-annual variability so that it is consistent with observations.
This study illustrates how future uncertainty of climate models in predicting hot extremes is controlled by two factors, both related to amplification of hot extremes through land-atmosphere interactions
The Heatwaves and Cold Air Outbreaks Research program has been very active, producing a considerable number of papers over the past four months.
