第7次南極地域観測隊気象部門報告 : 高層気象観測
Syowa Station was officially opened on February 1st, 1966 and routine upper observations by the use of newly-developed rawinsonde (Type RS II-64) were started on February 11th. By January 31st, 1967, 360 sondes in total were released at 1200 GMT, including 3 additional observations at 0000 GMT durin...

Stratospheric warming started on October 20th from the coast of east Antarctica. Accompanying the movement of the warming centre to the east, the warmed area expanded all over the continent.
