Explore a groundbreaking phenomenological model for studying the effects of general prescribed unsteady 3D flows on density-driven velocity components through temperature and salinity transport. Delve into the hybrid kinematic-dynamic model formulated as a non-linear, weakly coupled system of two non-local PDEs, which proves to be well-posed. Discover how this model bridges the gap between traditional dynamical Stommel Box models and kinematic models with chaotic advection mechanisms. Learn about the potential applications of this model in studying spatially dependent feedback processes in the ocean. Gain insights from the research conducted by Ori Saporta-Katz, Edriss S. Titi, Hezi Gildor, and Vered Rom-Kedar, as presented in their 48-minute talk at the Erwin Schrödinger International Institute for Mathematics and Physics during the Thematic Programme on "The Dynamics of Planetary-scale Fluid Flows."
