Climate

Definition of the domain

Climate modeling is to replicate more or less simplified the coupled behavior of the atmosphere, oceans and land surfaces at various spatial scales (from region to globe scales) or time (from season to century scales or more) . A useful tool for understanding the complexity of climatic phenomena is to numerically simulate the evolution coupled various components of the Earth system, after translating the physical principles governing the form of mathematical equations. CERFACS brings many strengths to meet this challenge by continuously improving the quality of these couplings, on more and more powerful computers , and analyzing in depth the results of many simulations it performs.

Challenges, issues and context

The intrinsic climate variability, from monthly to decadal scales, overlaps the global warming resulting from human activities. Detection of climate change and their allocation to various causes is a scientific problem that requires combining Earth observation, modeling of coupled and complex physical phenomena and scientific computing.

Cerfacs actively contributes to the IPCC exercises (Intergovernmental Panel on Climate Change) which regularly publishes a detailed report on the present climate and its projection throughout the century. Advances in climate modeling, in particular through the intensification of Earth observation and increasing computer power, reduce uncertainties in climate projections.

CERFACS scientist named in 2019 Clarivate ‘Highly Cited Researchers’ list

superadmin |  25 November 2019

Dr. Rosie Fisher, a researcher at CERFACS working on land surface modeling and terrestrial ecosystem dynamics, was named in the 2019 Web of Science "Highly Cited Researchers" list, which recognizes influential researchers of the past decade, as demonstrated by the authorship of highly-cited papers that rank in the top 1% by citations. Dr Fisher has been working in the Global Change group (GLOBC) at CERFACS since 2018 as part of a collaboration with the National Center for Atmospheric Research (NCAR) in Boulder, Colorado, where she was formerly a staff scientist.Read more


Sparse Days 2020

Brigitte Yzel |  25 November 2019

Sparse Days Meeting 2020 at Cerfacs, Toulouse June 11th-12th, 2020     The annual Sparse Days meeting will be held at CERFACS in Toulouse on 11th and 12th June 2020.  Registration for the Sparse Days is free but we ask people who are coming to register as soon as possible although the deadline is May 10th. Please register using the registration form. Although an emphasis will be on parallel aspects, any talk that has an association with sparsity is welcome. The length for a talk plus questions is 30 minutes although this is negotiable in either direction. Information on accommodation can be found on the web page.Read more
