Abstract: Based on the objective analysis scheme of the grid points of longitude and latitude, some experiments of incorporating unconventional data of satellite wind, reconnaissance aircraft, buoys and surface ship reports have also been analyzed. The analysis quality of this scheme has been examined. The results show that the incorporation of above-mentioned unconventional data is very important for the improving analysis quality. Especially for the Pacific and Atlantic areas where the convention data are relatively sparse, the objective analysis is significantly improved.
