Abstract
This paper is devoted to the studies of the possibility of the existence of strongly localized nonlinear structures in a rotating plasma filament. It was established that electromagnetic, drift-Alfven and drift-balloon waves in cylindrical plasma traps are self-organizing in a form of two-dimensional solitary vortices. The wave field consists of a single monopole or a pair of vortices of nonequal intensity, which move over the circular trajectory along azymuth. The analysis was performed both for the plasma of finite pressure and that of low pressure with account of the effect of finite Larmor radius of ions in the field of the gravity. The vortices contain the trapped particles which, moving in plasma, can affect the processes of the transport in the plasma traps as well as the collective processes in a magnetospheric plasma.
