冬季の総観規模擾乱に伴う南極昭和基地の昇温現象
It has been reported before that Antarctic temperature suddenly rises especially at surface when synoptic scale distubance arrives. Authors have examined the mechanism of this warming by the data observed at Syowa Station in mainly 1993 by the 34 th Japanese Antarctic Research Expedition (JARE 34)....
