Acoustic remote sensing of planetary boundary layer dynamics near Ross Island, Antarctica

An acoustic sounder (sodar) was used to analyze the locking effect of Ross Island and Hut Point, Antarctica, and its daily fluctuations. The results of the sodar estimation were used to determine the nature and habit of northwesterly winds. Fluctuations in atmospheric current causes a change in direction of northeast and southeast winds to northwest winds, which changes upstream katabatic drainage flow. The structure and habit of stable planetary boundary layer were also studied.
