Dipolar Geophysical Vortices: Coastal Eddies and Mesoscale Ocean Dipoles

Explore the dynamics of planetary-scale fluid flows in this 48-minute talk by Edward Johnson at the Erwin Schrödinger International Institute for Mathematics and Physics. Dive into two fascinating problems: coastal eddy propagation along a shelf and the widespread presence of mesoscale dipoles in the global ocean. Examine the generation of shelf wave wakes and energy flux from vortices, and discover analytic predictions for vortex evolution. Investigate steady vortex solutions and their parameter dependence. Learn about a novel solution for multipoles in surface quasi-geostrophic equations, explaining observed features of oceanic dipoles. Gain insights into the three-dimensional structure of these dipoles and their role in vertical exchanges within the ocean.
