Highquality wind observation on sea surface is the foundation of marine meteorological monitoring and forecasting. The accuracy of satellite retrieved winds along coast is low. The exponent law representing wind profile near surface layer is used to retrieve winds on sea surface around islands or mudflats on which automatic weather stations have been set up. Then objective analysis method is used to transform retrieved winds at discrete points into regular mesogrid to get complete wind field with high resolution. The accuracy of retrieved winds is determined by the parameter α in exponent law which is influenced by the status of underlying surface and atmosphere structure. The influence of the latter is more significant than the former. Experiments are performed to verify the error of retrieved winds calculated with different wind profile variation rates (parameter α). The results show that the accuracy of retrieved winds using multiple wind profile variation rates is better than that using single one. By using hybrid wind profile variation rates, mean error (ME), mean absolute error (MAE) and root mean square error (RMSE) of the overall sample are obtained, being 0.04 m·s-1, 1.51 m·s-1 and 2.01 m·s-1, respectively. Through optimizing retrieved winds on sea surface, MAE and RMSE are respectively reduced to 1.28 m·s-1 and 1.68 m·s-1.
