In order to provide the useful information for designing a wind turbine system in the area of cold Katabatic climate in Antarctica, analyzed were the wind data acquired at the 10m level during the course of operation for five years from 1987 to 1991 by Japan Meteorological Agency and National Institute of Polar Research, and measured continuously for the certain periods of hours in 1991 by the anemometer on top of the 6m tower next to the small wind turbine system at Asuka Observation Camp in Antarctica. Several findings were drawn based on the analysis of data. The duration time of the wind velocity specifically more than 10m/s in the direction of ESE lasted extremely long throughout a year. Gust factors kept almost constant in the range over the velocity of 8m/s. Power spectra have a peak value at 0.052Hz and were well approximated by the equation expressed under the condition of the neutral stratification.
