Abstract: Difficulties in the assimilation of Lagrangian data arise because the state of the prognostic model is generally described in terms of Eulerian variables computed on a fixed grid in space, as a result there is no direct ...

Abstract: Lagrangian measurements provide a significant portion of the data collected in the ocean. Difficulties arise in their assimilation, however, since Lagrangian data are described in a moving frame of reference that does not ...

Abstract: A basin-scale, reduced-gravity model is used to study how drifter launch strategies affect the accuracy of Eulerian velocity fields reconstructed from limited Lagrangian data. Optimal dispersion launch sites are found by ...

Abstract: Kinematic models predict that a coherent structure, such as a jet or an eddy, in an unsteady flow can exchange fluid with its surroundings. The authors consider the significance of this effect for a fully nonlinear, ...

Abstract: Cross-stream mixing and Lagrangian transport caused by chaotic advection within a baroclinic (2½ layer) meandering jet are investigated. The quasi-steady meanders arise as a result of evolution from an initial small-amplitude ...

Abstract: A single-layer, reduced-gravity, double-gyre primitive equation model in a 2000 km ? 2000 km square domain is used to test the accuracy and sensitivity of time-dependent Eulerian velocity fields reconstructed from numerically ...
