A variational theory of shearless transport barriers in unsteady dynamical systems
Tuesday, October 28, 2014, 12:00pm to 1:00pm | Room 5-314

The theory of Lagrangian Coherent Structures (LCSs) has advanced significantly over recent years, and now covers both hyperbolic and elliptic material surfaces in unsteady flow. Parabolic (i.e., jet-type) LCSs have, however, remained outside the reach of the theory, despite their significance in oceanic and atmospheric transport. Here I discuss a new variational approach to general shearless transport barriers in two-dimensional unsteady flows, which covers both hyperbolic and parabolic LCSs. I also describe a computational implementation of this new theory, and show applications to model flows and geophysical data sets.
