Abstract
Starting with nonlinear equations describing magnetic electron mode in a nonuniform, unmagnetized plasma with a spatially dependent flow, we derive a set of two coupled equations for the self-generated magnetic field and electron temperature perturbations. It is known that such a flow introduces some new terms in the corresponding evolution equations that, in the limit of a homogeneous plasma concentration are responsible for the creation of coherent stationary solutions in the form of chains of magnetic islands. However, keeping the appropriate terms describing the plasma inhomogeneity we find a new type of strongly nonlinear coherent solution in the form of a tripolar vortex. It is a structure consisting of a rotating central part with two satellites of opposite vorticity, placed in the sheared plasma flow and mowing with a velocity which equals the plasma flow velocity at the position where the tripole is created.
