Control and Dynamical Systems Seminar
Coherent Lagrangian Vortices in Unsteady Continua
Lagrangian Coherent Structures (LCSs) are special material surfaces that act as organizing centers for tracer patterns in unsteady continuum motion. In this talk, a review of recent results on elliptic LCSs (generalized KAM regions) that provide an objective way to define and locate coherent material vortices in turbulent flow data. Applications to geophysical data sets will be shown, including satellite altimetry of the ocean and a cloud-video footage of Jupitar.
