On Thursday, April 8, 2021, Gerald A Meehl (NCAR) presented a seminar, Mutually interactive decadal-timescale processes connecting the tropical Atlantic and Pacific.
In this study, CLEX researchers aimed to evaluate the effect of different sources of data and the uncertainties in satellite data, by comparing the data with a ground-based radar product using both location-based and storm-based approaches.
Major gaps exist in our understanding of the pathways between the generation and the breaking of internal waves in the Southern Ocean. This has important implications for the distribution of internal wave-driven turbulent mixing, for the sensitivity of ocean mixing rates, and for the representation of ocean mixing in numerical models.
Recent studies have debated whether the two types of sudden stratospheric warming – displacement events when the vortex is displaced off the Pole and split events when the vortex splits into two smaller vortices – have differing near-surface impacts.
CLEX researchers have constructed the oldest daily historical climate dataset for Perth, southwestern Australia, to provide an extended record for analysing pre‐industrial climate variability and extremes for the region.
An international team of researchers performed a systematic evaluation of simulations made by nine FireMIP models in order to quantify their ability to reproduce a range of fire and vegetation benchmarks.
Different expressions of El Niño do affect interannual variability in the terrestrial carbon cycle. However, the effect over longer timescales is small. This means the changing frequency of these two types of El Niño events may be of little importance in terms of robustly simulating the future terrestrial carbon cycle.
The discovery of changing eddy energy was made by a team of ANU and UNSW researchers from the ARC Centre of Excellence for Climate Extremes. Their work, published today in Nature Climate Change, shows clear changes to the distribution and strength of these eddies, which had not been previously detected.
In this report CMS welcomes Annette Hirsch to the team, alerts users to retracted ERA5 data, continues work on ACCESS-ESM1.5, and looks at changes to NCI processes, and CLEX data management practices and training.
The past few months following the mid-term review have seen a reorganisation of our research programs and a corresponding rearrangement of the website into these programs. Over the coming months, all previous research briefs will be shifted under the programs and regular research program meetings will be included in the Weekly Updates.
