| Zusammenfassung |
| Lagrangian drifters are a major source of data describing the features of fully developed turbulence in the ocean. We use a numerical primitive equation model in z-coordinates to study the kinematic information sampled by synthetic Lagrangian particles in baroclinically unstable zonal channel flows in the presence of a background planetary vorticity gradient. The objective is to characterize the sensitivity of Lagrangian statistics to changes in the background flow and corresponding changes in the dominant small-amplitude wave structures. The study is a first step in an attempt to link observational kinematic Lagrangian data to the dynamical mechanisms underlying the generation of fully developed turbulence in the ocean. |
