Abstract

This report describes the result of meteorological observations at Syowa Station by the Meteorological Observation Team of the 49th Japanese Antarctic Research Expedition (JARE-49) during the period 1 February 2008 to 27 January 2009. The observation methods, instruments, and statistical methods used by the JARE-49 team are nearly the same as those used by the JARE-48 observation team. Remarkable weather phenomena observed during the period of JARE-49 are as follows. 1) On 1 September 2008, the record minimum temperature for September was observed in the upper atmosphere (pressure greater than 175 hPa). 2) The monthly mean temperature at Syowa Station during October 2008 was - 17.5°C; this is the lowest monthly mean October temperature recorded at Syowa Station. 3) The total ozone over Syowa Station was less than or equal to 220 m atm-cm during the period from late August to late November, and was close to minimum levels during the period from mid-September to mid-October. The lowest total ozone in 2008, recorded on 16 October 2008, was 140 m atm-cm.
