Conditions for the Kelvin‐Helmholtz Instability in the Polar Ionosphere

Abstract The Kelvin‐Helmholtz instability can be excited by a velocity shear in a fluid. Inhomogeneous flows are frequently observed in regions with polar cap patches, reversed flow events and auroral arcs, that is, regions with irregularities that disturb navigation satellite signals. Understanding...
