The accumulation generally increased in late summer, winter and October at Syowa Station, and in late summer and winter at Mizuho Station. Its increase in late summer relies on the content of precipitable water and the increase in winter depends on the cyclones that approached the region. The increase in October at Syowa Station relies on the both factors. There is a large difference in the content of precipitable water between summer and winter, so the summer season plays an important role in snow accumulation at Mizuho Station rather than the winter season.}, pages = {1--11}, title = {南極沿岸部およびカタバ風帯の積雪量の変化-1979・80年の 昭和基地・みずほ基地の観測-}, volume = {85}, year = {1985}, yomi = {ワダ, マコト} }
