Lagrangian analysis is a powerful way to analyse the output of ocean circulation models and
other ocean velocity data such as from altimetry. In the Lagrangian approach, large sets of …

Chaotic dynamics can be considered as a physical phenomenon that bridges the regular
evolution of systems with the random one. These two alternative states of physical …

Coherent Lagrangian (material) structures are ubiquitous in unsteady fluid flows, often
observable indirectly from tracer patterns they create, for example, in the atmosphere and …

Chaos: from simple models to complex systems aims to guide science and engineering
students through chaos and nonlinear dynamics from classical examples to the most recent …

We review statistical analyses of Lagrangian data from the ocean. These can be grouped
into studies involving single particles and those with pairs or groups of particles. Single …

We characterize horizontal mixing and transport structures in the surface circulation of the
Mediterranean Sea, as obtained from a primitive equation circulation model. We calculate …

Different aspects of the predictability problem in dynamical systems are reviewed. The deep
relation among Lyapunov exponents, Kolmogorov–Sinai entropy, Shannon entropy and …

One of the ubiquitous features of real-life turbulent flows is the existence and persistence of
coherent vortices. Here we show that such coherent vortices can be extracted as clusters of …

▪ Abstract This article reviews the transport properties of coherent vortices in rotating
barotropic flows. It is shown that vortices induce regular Lagrangian motion inside their …

The Adriatic Sea surface circulation for the period 1990–1999 is studied using the data of
more than 200 satellite-tracked drifters. The spatial structure and the temporal variability of …
