A total of 18 stations, such as buoys, platforms and island stations in the Bohai Sea region are selected. The observed wind speed data at different anemometer height are adjusted to a reference level-10 m using COARE algorithm. The ASCAT retrieval sea wind is compared with the observed wind at stations. The statistical results show that the satellite wind speed is larger than that from observations of the three types of stations on the whole. The wind speed difference between buoys and the satellite is the smallest, while the difference is larger between platforms and island stations. The comparison of wind directions shows that the mean deviation of wind directions from the satellite and stations is very small, but the root mean square deviation (RMSD) is large. With the increase of wind speed, the mean speed deviation of the three types of stations decreases from positive to negative. The satellite wind speed is larger than that of stations during low wind speed, but the former is smaller than the latter during high wind speed. The RMSD of wind speed is relatively stable in regions of different wind speed. The RMSD of wind directions from the satellite and stations decreases with the increase of wind speed. The distinction between wind speed difference and wind direction deviation is small in different directions. For the seasonal variation, the mean difference between platforms/islands and the satellite is large in autumn and winter, but small in spring and summer.
