Measurements of snowdrifts and wind profiles around the huts at Syowa Station in Antarctica
The author joined in the 19th Japanese Antarctic Research Expedition and measured the forms and quantities of snowdrifts accumulated around the existing high floor huts (Observation Hut and Ionosphere Hut) located in the major part of Syowa Station. He also investigated the characteristics of the wi...
