Comparison of Wind Speed and Wind Stress in the Southern Ocean
The wind speed and wind stress over the Southern Ocean (SO) is compared from the QSCAT, COAPS, ERA-Int, JRA25 and NCEP2. From the results of comparison, NCEP2 seems to poorly represent wind speed in the SO. In the summer months, the difference of wind speed and wind stress between products is small...

The wind speed and wind stress over the Southern Ocean (SO) is compared from the QSCAT, COAPS, ERA-Int, JRA25 and NCEP2. From the results of comparison, NCEP2 seems to poorly represent wind speed in the SO. In the summer months, the difference of wind speed and wind stress between products is small while the bias during winter is larger. Also, the difference increases in the high latitudes, close to the sea-ice zone. South of 55°S, COAPS has weaker correlation of wind stress with reanalysis data. The major reasons of differences between products are associated with the impact of seaice and the differences of resolution, assimilation and parameters chosen from models.
