Abstract: detailed analysis of Lagrangian tracer dispersion is performed on datasets obtained from laboratory experiments that simulate rotating turbulence in the presence of a ? effect. Compatible with the limitations of the ...

Abstract: The authors show that long-term memory effects, present in the chaotic dispersion process generated by a meandering jet model, can be nonetheless taken into account by a first-order Markov process, provided that the states ...

Abstract: A 3D multiscale kinematic velocity field is introduced as a model to simulate Lagrangian turbulent dispersion. The incompressible velocity field is a nonlinear deterministic function, periodic in space and time, that ...

Abstract: Mixing and transport in correspondence of a meandering jet are investigated. The large-scale flow field is a kinematically assigned streamfunction. Two basic mixing mechanisms are considered separately and in combination: ...

Abstract: The EOLE experiment is revisited to study turbulent processes in the lower stratosphere circulation from a Lagrangian viewpoint and to resolve a discrepancy on the slope of the atmospheric energy spectrum between the work ...

Abstract: n the framework of Monitoring by Ocean Drifters (MONDO) project, a set of Lagrangian drifters were released in proximity of the Brazil Current, the western branch of the subtropical gyre in the South Atlantic Ocean. The ...
