LAGRANGIAN COHERENT STRUCTURES: FROM JELLYFISH TO HURRICANES
Lagrangian Coherent Structures (LCS) are the time varying generalization of separatrices, which divide the space of a dynamical system into trajectories that have different dynamical behaviors. For example, in a jellyfish, which fluid particles will get entrained into the jellyfish and which will be used for propulsion? Similarly, what fluid parcels will get entrained into a hurricane and which will get detrained?
LCS answers these and other types of questions through the use of recently developed theoretical and computational methods in dynamical systems.
