Carriers of \emph{Sargassum} and mechanism for coastal inundation in the Caribbean Sea
F. Andrade-Canto, F. J. Beron-Vera, G. J. Goni +3
We identify effective carriers of \emph{Sargassum} in the Caribbean Sea and describe a mechanism for coastal choking. Revealed from satellite altimetry, the carriers of \emph{Sarga…
Heat-content and diffusive leakage from material sets in the low-diffusivity limit
Nathanael Schillling, Daniel Karrasch, Oliver Junge
We generalize leading-order asymptotics of a form of the heat content of a submanifold (van den Berg & Gilkey 2015) to the setting of time-dependent diffusion processes in the limi…
A Lagrangian perspective on nonautonomous advection-diffusion processes in the low-diffusivity limit
Daniel Karrasch, Nathanael Schilling
We study mass preserving transport of passive tracers in the low-diffusivity limit using Lagrangian coordinates. Over finite-time intervals, the solution-operator of the nonautonom…
Genesis, evolution, and apocalypse of Loop Current rings
F Andrade-Cano, D. Karrasch, F. J. Beron-Vera
We carry out assessments of the life cycle of Loop Current vortices, so-called rings, in the Gulf of Mexico by applying three objective (i.e., observer-independent) coherent Lagran…
Fast and robust computation of coherent Lagrangian vortices on very large two-dimensional domains
Daniel Karrasch, Nathanael Schilling
We describe a new method for computing coherent Lagrangian vortices in two-dimensional flows according to any of the following approaches: black-hole vortices [Haller & Beron-Vera,…
Barriers to the Transport of Diffusive Scalars in Compressible Flows
George Haller, Daniel Karrasch, Florian Kogelbauer
Our recent work identifies material surfaces in incompressible flows that extremize the transport of an arbitrary, weakly diffusive scalar field relative to neighboring surfaces. S…
