Apparaît dans la collection : 2026 - T2 - WS3 - Idealised mathematical models for geophysical flows

In this talk I will describe recent results using asymptotic analysis to create a simple reduced model for strongly stratified turbulence (driven by horizontal body forces) across parameter space, together with Direct Numerical Simulations that validate the model. More specifically, the model leverages the anticipated flow anisotropy in the limit of small Froude number / large Reynolds number to derive scaling laws for the turbulence properties. Several distinct regimes are investigated.
