摘　　要：海洋初值的形成,是开展海洋数值预报的关键问题之一,在我国的海洋预报研究中,它还是一个新课题。本文从海洋观测现状出发,对海洋初值形成的主要环节及其有关理论和处理方法进行了初探,它包括大洋资料选取、资料质量控制、客观分析、初值化及四维同化等5个方面。作为举例,对SST(海表温度)模式的初值形成方法进行了阐述,实际应用表明该方法是稳定而有效的,尽管是初步的。The formation of initial values is a critical problem in oceanogrphic prediction and is a rather new subject in China. Based on the present condition of ocean observations, the principal links and existing problems in the formation of initial values are approached tentatively in the paper. The links discussed consist of the varieties of oceanographic observations, the quality control of data, objective analysis, initialization and four-dimensional data assimilation. As an example, the method of formation of initial values established in the SST prediction model is elucidated, and has been proved to be stable and effective, though the method is preliminary.
