Meteorological Observations at Syowa Station in 1980 by the 21st Japanese Antarctic Research Expedition

Abstract

This paper describes the results of meteorological observations (mainly surface and aerological) at Syowa Station from February 1,1980 to January 31,1981. The new processing system for the weather data (AMOS : Automated Meteorological Observation System) was set up in January 1980,and the automated upper-air observation by means of this system began in February 1980. Remarkable characteristics are as follows : 1) The temperature remained high through the year. The mean temperature of 1980 was 2.2℃ higher than the normal, which was the highest value since our observation had started. 2) Sea ice around Ongul Islands flowed away due to the heavy blizzard which hit on March 17-18,1980. This phenomenon was the first experience since Syowa Station had been established.
