67 climate modelling groups use OASIS3-MCT to assemble more than 80 coupled applications

10 September 2019

OASIS3-MCT is a coupler of codes developed at Cerfacs and used around the world, mainly for climate modelling applications. Our last survey confirms that OASIS3-MCT is used by 67 modelling groups to assemble more than 80 different coupled applications over the 5 continents. These applications include global or regional configurations of ocean and atmosphere models but also sea ice, sea level, wave, ocean biogeochemistry, land, vegetation, river routing, hydrological and atmospheric chemistry models. OASIS3-MCT is used in 5 of the 7 European Earth System Models participating to the 6th Coupled Model Intercomparison Project (CMIP6) that produces the climate simulations forming the basis of the next report of the Intergovernmental Panel on Climate Change (IPCC)” Read more

Sanderson, B.M., Wobus, C., Mills, D., Zarakas, C., Crimmins, A., Sarofim, M.C. and Weaver, C., Informing future risks of record‐level rainfall in the United States. Geophysical Research Letters.

24 April 2019

The changing risk of extreme precipitation is difficult to project. Events are rare by definition and return periods of heavy precipitation events are often calculated assuming a stationary climate. Furthermore, ensembles of climate model projections are not large enough to fully categorize the tails of the distribution. We propose a clustering algorithm to identify self‐similar hydroclimates to estimate changes in the expected frequency of extremely rare events under scenarios of global mean temperature change. We find that, although there is some regional variation, record events are projected in general to become more intense, with 500 year events intensifying by 10‐50% under 2°C of warming and by 40‐100% under 4°C of warming.

IMFT and CERFACS win a second ERC (European Research Council) advanced grant in combustion !

3 April 2019

The latest results of the 2018 ERC have been announced: IMFT (Institut de Mécanique des Fluides de Toulouse) and CERFACS have won a second ERC advanced grant in the field of combustion: . This 2.5 Meuro grant will allow to study hydrogen combustion for the storage of renewable energies using experiments (at IMFT) and simulations (using CERFACS tools). This is the second ERC advanced grant obtained by IMFT and CERFACS after the INTECOCIS project in 2013 (intecocis.inp-toulouse.fr) and it confirms the unique place of Toulouse in the world of combustion.

Cerfacs rewarded by two prices at the Safran Aircraft Engines R&T day – 17 December 2018

19 December 2018

On Dec 17th, Cerfacs participated to the R&T Safran Aircraft Engines day during which Safran AE and their partners presented their research and development work. Cerfacs research was presented on various posters providing a general overview of numerical simulation activities performed with Safran in the fields of combustion chamber, compressor, turbine and numerical methods. Five CERFACS Phd student (CIFRE) also presented their work in 180 seconds. Over the 6 prices attributed to Safran AE partners, Cerfacs was awarded by the contract agility price. This price was awarded for the partner delivering fast responses to consultations and allowing quick and easy contract setup. Finally, Félix Collin-Bastiani received a prize for  his Phd research on modeling and simulation with large eddy simulation of ignition processes in two-phase flow and real-world conditions.

Professor Andrea Saltelli Seminar at CERFACS, December 3rd, 2018 Summary

4 December 2018

CERFACS was pleased to welcome Pr. A. Saltelli for a wide interest seminar an Uncertainty Quantification. Pr. Andrea Saltelli's main disciplinary focus is on sensitivity analysis. The main idea behind sensitivity analysis is to figure out how the uncertainty in the output of a model can be apportioned to different sources of uncertainty in its inputs. Pr. Saltelli has worked on various fields of application such as physical chemistry, environmental sciences, applied statistics, impact assessment and science for policy. At present he is adjunct professor at the Centre for the Study of the Sciences and the Humanities at University of Bergen. He is currently a visiting fellow at Open Evidence Research at the Universitat Oberta de Catalunya in Barcelona. The talk was entitled "Are the results from a particular model more sensitive to changes in the model and the methods used to estimate its parameters, or to changes in the data". It reviewed some principles of sensitivity analysis, good and bad practices, and some practitioners' insight on when to use what. The stream line for the talk is available here Read more
