Over-reflection of hydromagnetic planetary-gravity waves at the solar helmet streamers and magnetic sectors

Overreflection of propagating hydromagnetic planetary-gravity waves incident on the current sheets of the helmet streamers and magnetic sectors of the solar corona is investigated. It is shown that overreflection arises only if the wavenumbers, or the energy fluxes per unit mass, perpendicular to th...

description Overreflection of propagating hydromagnetic planetary-gravity waves incident on the current sheets of the helmet streamers and magnetic sectors of the solar corona is investigated. It is shown that overreflection arises only if the wavenumbers, or the energy fluxes per unit mass, perpendicular to the current sheet of the incident and the transmitted waves in both cases are in opposite directions. The overreflected waves then draw magnetic energy from the Sun's field and communicate it to the interplanetary magnetic field.
