Climate modeling and Global change (GLOBC)

Simulating the climate system dynamics

CERFACS conducts fundamental and applied research in the field of climate modeling and its global change. The “Climate modelling and global change” team (GLOBC) participates in the development of coupled models between the oceans, the atmosphere and the other components of the climate system. Numerical simulation of the evolution of these systems requires the use of high performance computers in order to correctly represent sufficiently fine spatial and temporal scales to reproduce the dynamics of the observed climate. Many simulations are carried out through various research projects and the analysis of the results leads to numerous publications in international journals. The DECLIPP challenge details a research strategy focuses on climate variability on decadal time scales.

To develop high level softwares

The team strategy is based on a dual approach combining theoretical modeling studies and on the development of high-level softwares, such as, for instance,  the   OASIS and OpenPALM couplers, needed to address the various linkages involved in climate science or in multi-physical / multi-component industrial applications.

To contribute to transverse axes

In continuation of this theme,   hydrology and hydraulics are leading areas of research, largely oriented towards the calculation of  uncertainties and  data assimilation. These activities contribute, in collaboration with other teams at Cerfacs,  to the MODEST challenge. All this research takes place through the coordination and participation in national and international research programs.

For many years, the team is associated with the National Centre for Scientific Research (CNRS) through the UMR CECI 5318 research unit.

Tribute to Françoise Chatelin

Brigitte Yzel |  23 July 2021

  Tribute to Françoise CHATELIN   Virtual & Face to Face event @ Cerfacs 14 October 2021, CERFACS, Toulouse (France) 2 pm - 6.30 pm   Cerfacs is organizing a half scientific day on Thursday October 14, 2021 in tribute to Françoise Chatelin who left us prematurely on May 14, 2020   After graduating from the Ecole Normale Supérieure in Paris (1960-63), and her PhD in Mathematics at Grenoble University (1971) , Françoise Chatelin led with worldwide recognition her research in many areas, from spectral theory for linear operators in Banach spaces and finite precision to Dickson algebras. Professor Chatelin taught at the Universities Grenoble 2 - Pierre Mendès-France and Paris 9 - Dauphine before moving to Toulouse in 1996. She became Emeritus Professor in 2015. She was a visiting researcher at Berkeley and Stanford Universities, IBM San Jose (Ca) and Yorktown Heights (NY). For almost a decade, she was a scientific manager in Industry (in charge of intensive computing) first at the Centre Scientifique IBM France in Paris (1985 -1992) and then in the Central Research Lab of Thales (known as Thomson-CSF at that time) near Paris (1992-95). Françoise Chatelin was Head of the Qualitative Computing group at the Centre Européen de Recherche et de Formation Avancée en Calcul Scientifique (Cerfacs) in Toulouse, France. Professor Chatelin has authored four books; the first three are now classic references available from SIAM. Her second book Valeurs Propres de Matrices (Masson, Paris, 1988) has received the IBM - France prize for « Best Scientific and technical publication 1988 ». Beyond her scientific contribution, Françoise Chatelin played a structuring role on research at CERFACS through multiple thesis on innovative topics. This event is devoted to the human and scientific tribute of her life. As a faithful image of the active and passionate woman that...Read more

CERFACS is involved in the NextSim project

CERFACS |  19 July 2021

The primary objective is to increase the capabilities of Computational Fluid Dynamics tools on extreme-scale parallel computing platforms for aeronautical design. The Kick-Off Meeting took place on 12 March 2021. This project has received funding from the European High-Performance Computing Joint Undertaking (JU) under grant agreement N° 956104. The JU receives support from the European Union’s Horizon 2020 research and innovation programme and Spain, France, Germany.
