摘　　要：利用LEVITUS方法对中国近海及邻近海域历史观测的温度和盐度资料进行客观分析,生成累年各月标准层1/2°×1/2°的格点数据集?文中选择给出一些深度标准层次上的平面等值线图?并用该方法分析船舶观测 SST数据,将其分析结果应用于中国近海海表面温度短期数值预报的变分伴随资料同化试验中,表明资料的客观分析对海洋数值模拟和预报的重要性?Nansen temperature and salinity data are objectively analyzed to produce a data set at standard depths on a 1/2°×1/2°grid for each of the twelve months in China Seas. The methods developed by Levitus for the world ocean are the basis of our analysis. Horizontal contour plots at selected depths are presented. Further more similar analytical results of Sea Surface Temperature (SST ) ship report data are applied to the adjoint assimilation experiment for the short-term forecasting of SST in China seas. It is showed that the analyzed gridded data set is virtual to satisfy the need of the modeling and other uses.
