    Continuous density variations in the ocean

    5 février 2026 - 11:00Salle de conférences IRMA

    The aim of this talk is to study the well-posedness of the incompressible Euler equations in an oceanic setting, including continuous density variations. Because of specific features of our setting (presence of a free-surface, small scale ratios, i.e. the shallow water parameter), a first approach will consist in studying the case of small density variations, which will lead to the justification of the well-known non-linear shallow water equations. We then move to a case where large density variations can be studied, which is when the density is strictly decreasing with height. This setting of so-called stable stratification is widely used in the study of geophysical flows, and is one of the main ingredients that contribute to the global oceanic circulation, regulating the Earth' climate.
