Description

It is proposed that whistler ducts, field aligned ionization enhancements in the plasmasphere, are the direct result of a positive feedback loop coupling the plasmasphere and ionosphere. Estimated sizes are in accord with experimental data and whistler duct movement is shown to be a natural consequence of the theory. During their formation large fluxes of electrons will be precipitated - thus accounting for the observed anomalous electron precipitation accompanying whistler mode waves. Ionospheric irregularities will also be associated with whistler ducts.
