Consideration is given to a system of point vortices and the effects of finite-area vortices are
examined in terms of vortex patches. Vortex points, sheets, and patches are noted to be …

Numerical studies of the Hasegawa—Mima equation, derived in the context of drift waves
but equivalent to the quasi-geostrophic vortex potential equation for Rossby waves, show …

A tripolar vortex, three aligned vortices with alternate signs of polarity of rotation, has been
observed in a plasma for the first time. The tripolar vortex always appears with a deep …

An analysis of waves and instabilities in the recently created pair-ion plasma is presented.
The pair-ions,, have the same mass and opposite charge. In the case of an unmagnetized …

The equations of motion for point vortices are well known to preserve certain discrete
symmetries of the initial state. The case of a center of symmetry is considered in detail here …

Drift vortices in plasmas described by the Petviashvili equation in the case of strong
temperature inhomogeneities or by the Hasegawa–Mima equation in the case of density …

The material provides an historical background to forecasting developments as well as
introducing recent advances. The book will be of interest to both mathematicians and …

AsTRACT we obtain an exact nonlinear stationary solution for barotropic waves in a 6-plane
channel and show that it can be excited under a range ofinitial conditions. Results show that …
