CEMRACS 2019: Geophysical fluids, Gravity flows
The CEMRACS is a scientific event of the SMAI (the French Society of Applied and Industrial Mathematics). The concept was initiated in 1996 by Yvon Maday and Frédéric Coquel and takes place every year at CIRM in Luminy (Marseille, France) during 6 weeks from mid-july. The goal of this event is to bring together scientists from both the academic and industrial communities to work and discuss on focused topics. During the first week, a classical summer school is proposed. It consists of several lectures given by leading scientists and related to the topics of the research projects. The remaining 5 weeks are dedicated to working on the research projects, possibly after a morning seminar. CEMRACS 2019 intends to focus on modelling, analysis and numerical simulation of geophysical flows. Human activity has greatly diversified and intensified over the last few decades, leading to the emergence of new ecological, social and economic challenges. In this context, considerable progress has been made by scientists in trying to analyse, predict or even control a number of natural phenomena. The contribution of mathematical analysis and modelling is a major asset in understanding these problems, and has allowed, among other things, the development of operational numerical methods, based on current predictive models. However, these recent challenges (development of renewable energy sources, intensification of extreme events, impact of ocean and atmospheric currents, etc.), with their growing impact on populations and significant economic spinoffs, maintain the need for faster and more accurate predictions. Even today, these motivations still come up against theoretical and technical limitations. Great advances remain to be done, both in terms of model analysis and precision, and efficiency and accuracy of numerical schemes.
