This study investigated the flow characteristics altered by Jang Bogo Antarctic Research Station using computational
fluid dynamics (CFD) modeling. The topography and buildings around Jang Bogo Station were constructed with computeraided-design
data in the CFD model domain. We simulated 16 cases with different inflow directions, and compared the flow
characteristics with and without Jang Bogo Station for each inflow direction. The wind data recorded by the site’s automatic
weather station (AWS) were used for comparison. Wind rose analysis showed that the wind speed and direction after the
construction of Jang Bogo Station were quite different from those before construction. We also investigated how virtual wind
fences would modify the flow patterns, changing the distance of the fence from the station as well as the porosity of the
fence. For westerly inflows, when the AWS was downwind of Jang Bogo Station, the decrease in wind speed was maximized
(−81% for west-northwesterly). The wind speed reduction was also greater as the distance of the fence was closer to Jang
Bogo Station. With the same distance, the fence with medium porosity (25%–33%) maximized the wind speed reduction.
These results suggest that the location and material of the wind fence should be selected carefully, or AWS data should be
interpreted cautiously, for particular prevailing wind directions.
