A review of classical percolation theory is presented, with an emphasis on novel
applications to statistical topography, turbulent diffusion, and heterogeneous media …

Several simple mathematical models for the turbulent diffusion of a passive scalar field are
developed here with an emphasis on the symbiotic interaction between rigorous …

The atmosphere and ocean are two of the most important components of the climate system,
and fluid dynamics is central to our understanding of both. This book provides a unified and …

These lecture notes are based on a tutorial given in 2017 at a plasma physics winter school
in Les Houches. Their aim is to provide a self-contained graduate-student level introduction …

This paper formulates tracer stirring arising from the Gent–McWilliams (GM) eddy-induced
transport in terms of a skew-diffusive flux. A skew-diffusive tracer flux is directed normal to …

Mixing is the operation by which a system evolves under stirring from one state of simplicity—
the initial segregation of the constituents—to another state of simplicity—their complete …

We investigate the spreading of passive tracers in closed basins. If the characteristic length
scale of the Eulerian velocities is not very small compared with the size of the basin the …

The method of multiple time scales is used to obtain an approximate description of the linear
propagation of near-inertial oscillations (NIOs) through a three-dimensional geostrophic …

We present power spectra of time-series data for tree ring width chronologies, atmospheric
temperatures, river discharges and precipitation averaged over hundreds of stations …

Superdiffusive behavior, ie,〈 x2 (t)〉∼ t2ν, with ν> 1/2, is in general not completely
characterized by a unique exponent. We study some systems exhibiting strong anomalous …
