Lagrangian Analysis and Forecasting in the Oceans and Coastal Zones.

摘要

The goal of this research program is to develop a more detailed and systematic understanding of transport and mixing in the oceans and coastal zones. Ultimately, the program will lead to Lagrangian forecasting, that is, the ability to make specific deterministic predictions about the advection and diffusion of passive scalars in the ocean. To accomplish this, it will be necessary to unify several rapidly advancing areas: aspects of dynamical systems theory developed to identify transport barriers and coherent Lagrangian structures, Lagrangian stochastic models of turbulent diffusion, and Eulerian observation data, e.g. sea surface height (SSH) from the TOPEX/Poseidon altimeter for global/regional studies and high frequency (HF) radar for coastal studies.
