 note = {P(論文), The influence of the solar wind on the precipitation of high energetic particles into the middle atmosphere has been investigated by means of ionospheric absorption data measured during the participation of three GDR-groups in the 21st-23rd Soviet Antarctic Expeditions at the Soviet Antarctic Station Novolazarevskaya and by means of other ionospheric and geomagnetic data from high and middle latitudes. It could be shown that the energy transfer function ε as introduced by PERREAULT and AKASOFU (Geophys. J. R. Astron. Soc., 54,547,1978) is a good quantity to describe the energy transfer from the solar wind into the magnetosphere and ionosphere as demonstrated by a comparison of the longterm variation of ε with the variation of the geomagnetic Ap-index and the excessive particle-induced absorption in mid-latitudes. A correlation analysis confirms also the significant connection between hourly values of different geomagnetic indices and of ionospheric absorption data from high latitudes with the energy transfer function ε and suggests a time delay of particle injection into the magnetospheric ring current and the precipitation into the ionosphere of about one hour in relation to ε. Investigations of individual geomagnetic storms in midlatitudes demonstrate that the particle precipitation during the main phase of the storm is markedly controlled by the energy transfer function, whereas during the post-storm phase the internal magnetospheric processes play an important role, too.},
