摘　　要：以海洋原始方程组为基础,用SST常规船舶资料形成初始场,以气象预报产品提供海表面的强迫场,建立了一个有限区域的SST短期(3～5d)动力数值二维预报模式,开创了第一代SST短期数值预报模式.利用此模式进行了试预报,预报效果良好,实现了表层海水温度数值预报业务化运行,实效为3d的预报精度均方误差达到1.0℃左右.Based on the original equation of sea, the numerical model was built up. The initial temperature and salinity fields of the model came from the SST data of routine shipping; The force field on the sea surface came from the production of weather forecast. We built a dynamical planar numerical model for predicting the SST (3~5 days) of a finite area; We created the first generation short-range SST numerical predicting model. The model was tested, the result was all right, the SST numerical predicting was carried out. The Mean Square Error of the third day predicted was about 1.0℃
