This paper describes the results of meteorological observations (mainly surface and aerological) at Syowa Station from February 1,1984 to January 31,1985. Methods and equipment for observations are the same as in 1983. The observed data were sent to World Meteorological Center at Melbourne via Mawson Station according to the WMO Regulations. Remarkable characteristics are as follows : 1) On May 7 to 8,1984,we had rainfall for about 6 hours. Rainfall in May was observed for the first time. 2) Fine weather continued from middle of November to late December. Monthly total amount of sunshine duration of December was 594.5 hours, which was the maximum record at Syowa Station. 3) Atmospheric turbidity was higher than the normals, and annual mean value was the highest since observation had begun at Syowa Station.
