Global vortex pattern in a rotating plasma

A set of nonlinear fluid equations that include the effect of finite ion Larmor radius is derived to describe the dynamics of flute modes in a rotating inhomogeneous plasma with a strong axial magnetic field. It is shown that these equations possess a solution in the form of a global pattern of two‐...

Zusammenfassung:	A set of nonlinear fluid equations that include the effect of finite ion Larmor radius is derived to describe the dynamics of flute modes in a rotating inhomogeneous plasma with a strong axial magnetic field. It is shown that these equations possess a solution in the form of a global pattern of two‐dimensional vortices, different from the solitary vortex structure found earlier for the nonlinear Rossby waves.
