BRIEF RESULTS OF THE WEATHER ANALYSIS DURING THE RELIEF OPERATION OF J.A.R.E. IV, 1959-60
1. Introduction The expedition ship "SOYA" was manned by three meterologists, who were in charge of weather forecasting for the operation as well as of regular ship surface observations and occasional radio-sonde observations. The weather analysis was made twice a day on the basis of the s...

1. Introduction The expedition ship "SOYA" was manned by three meterologists, who were in charge of weather forecasting for the operation as well as of regular ship surface observations and occasional radio-sonde observations. The weather analysis was made twice a day on the basis of the synoptic charts, 0600Z and 1800Z, which cover the whole southern hemisphere. This paper briefly reports the results of the analysis with respect to the area limitted between 40°W and 80°E. 2. Distinctive features of the synoptic pattern of this season a) A superior southward extension of subtropical anticylone was seen in January. b) The influence of the Antarctic continental anticyclone was predominant in middle December and in February. c) The change of weather phenomena in the vicinity of Lutzow-Holm Bay was considerably regular. d) There were two periods of conservative stable weather in the Antarctic coastal region, late December and early February.
