摘要: We have constructed a theory for standing Alfven waves driven in the magnetosphere by monochromatic source localized ionosphere. It is shown that dominant role such oscillations played harmonics with large azimuthal wave numbers m ≫ 1. explore possibility of being excited during active experiments on periodic (with period eigenmodes magnetosphere) ionospheric modifications. Our study has made it apparent measured distance between local maxima amplitude an experiment can be used to infer value polarization splitting spectrum poloidal and toroidal magnetosphere.
