We consider the relationship between modal representations obtained from data-driven decomposition methods and Lagrangian Coherent Structures (LCSs). Mode sensitivity is used to describe this analysis as an extension of the model sensitivity framewor

The simulation of many complex phenomena in engineering and science requires solving expensive, high-dimensional systems of partial differential equations (PDEs). To circumvent this, reduced-order models (ROMs) have been developed to speed up computa
