Kelvin‐Helmholtz Instability in the Geotail Low‐Latitude Boundary Layer

The low‐latitude boundary layer stability problem in the geotail is solved numerically. This study relies on a cylindrical model of the geotail, with a smooth boundary, enwrapped by a helical solar wind flow. It is shown that three types of unstable magnetohydrodynamic waves exist in this plasma sys...
