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.

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

superadmin |  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
