 note = {P(論文), Radiosonde observations at Syowa Station, Antarctica (69°S, 40°E), are analyzed to find the stratospheric and tropospheric influence of solar-terrestrial phenomena in 1967-1993. Although the level of statistical significance is generally low, mean temperature changes of 1-2℃ are seen after solar proton events; these include transient warming in the lower stratosphere and cooling in the troposphere. The most significant temperature changes appeared during the East phase of quasi biennial oscillation (QBO<0). The presence of a weak correlation with the phase southern oscillation index (SOI) is also suggested. Only very low-level correlations are found for Forbush decreases of galactic cosmic rays and geomagnetic activities.},
