The Role of Neutral Winds in Polar Cap Patch Instability Growth

Journal of Geophysical Research: Space Physics
Abstract Polar cap patches are regions of dense plasma in the polar cap that convect from noon to midnight, moving against the neutral gas background. The gradient drift instability (GDI) destabilizes the edge of these patches as they convect, yet the rate of this destabilization is not well known due to the scarcity of coincident ...
