Development and Application of Dynamical Systems Techniques for Use With Ocean Data

Abstract

Various aspects of the Eulerian and Lagrangian predictability of oceanographically relevant flows are examined using models and data. For the problem of Lagrangian predictability, such as in search-and-rescue operations, dynamical systems techniques are used to determine the distributions of chaotic versus regular behavior in models of jets and recirculations. Eulerian predictability is addressed using phase space reconstruction of time series from models and hierarchy of oceanographic data sets. Uncertainty in flows in regions of complex, unresolvable topographic variations is examined using a porous medium approach.
