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.

 

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 application and transverse axes

The GLOBC team is particularly involved in the following application areas

These application areas feed and are fed by the following transversal areas:

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.

ISAF project : To accelerate the transition to SAFs, SAFRAN and CERFACS have together obtained an allocation of 44 million CPU hours on the LUMI-C super-computer as part of the EuroHPC Regular Access call in November 2022.

CERFACS |  11 March 2023

The objective of the ISAF project is to study the impact of SAFs (Sustainable Aviation Fuels) on engine operation and pollutant emissions, using high-fidelity Large Eddy Simulations (LES). The methodology developed at CERFACS combines Analytically Reduced Chemistry (ARC) with a multi-component evaporation model to capture the effect of fuel. The target configurations range from academic burners (CRSB at CORIA, SSB at DLR Stuttgart), to isolated industrial injection systems (MICADO at ONERA, HERON at CORIA) and complete annular combustor configurations (BEARCAT at SAFRAN, NTNU test bench).Read more
