Abstract
Variations of the solar surface and the interplanetary space that are responsible for the reported response in the lower atmosphere to the solar sector boundary (SSB) passages are discussed. Special attention is paid to elucidate the facts that the atmospheric response occurs 5 days before the SSB passages and is found only in the 8 winters from 1964 to 1972. The geomagnetic index Kp and the intensity of the galactic cosmic ray are used as the monitor of the corpusqular radiation and the 10.7cm solar radio flux intensity is used as the monitor of X-ray and EUV range intensity. The variation of the visible range is considered to be negligibly small.
Although the corpusqular radiation is closely related to the SSB passage, the starting day and the solar cycle dependence of its variation do not accord with those of the reported atmospheric response. The 10.7cm flux does not have the physically controlled variation around the SSB passages. However, the 10.7cm flux intensity had been accidentally and significantly weak during 8 days before the SSB passages in the 8 winters in the period from 1964 to 1972. The period and the starting day of this variation is perfectly in accord with those of the reported atmospheric response.
