Turbulence is everywhere -- it rattles our airplanes and makes tiny whirlpools in our bathtubs -- but it's one of the least understood phenomena in physics.Turbulence occurs when an ordered fluid flow...

We present an overview and some new results on anomalous diffusion of passive scalar in turbulent flows (including those used by Richardson in his famous paper in 1926). The obtained results are based...

Many vital insights into the nature of turbulence in fluids have originated from experimental data obtained in geophysical flows. Geophysical data have often helped to stimulate the creation of new tu...

Long-time evolution of large-scale geophysical flows is considered in a β-plane approximation. Motions in an infinite 2-layer model ocean are treated as a system of weakly nonlinear Rossby waves (weak...

Much progress in understanding the coupling between the atmosphere and the sea has been made
during the past years. Here we discuss the implications of the recent discovery of enhanced (above wall la...
