摘要：

本文开发出一套与三维温盐流数值模式POM相匹配的最优插值数值同化模块,具有将船舶报资料和Argo海温数据加入数值模拟的能力。利用该同化系统,本文对2001～2002年进行了数值模拟试验,通过模拟结果和未加入同化的模拟结果的对比表明,该同化系统能有效地改进三维海温模拟结果,使之更为接近于观测值。

In this paper,an oceanic data assimilation module based on optimal interpolation is developed for a 3-dimensional ocean model(POM).Some experiments are designed to test the module’s correctness and feasibility.By using the ocean observating data of ARGO and volunteer ship from 2001 to 2002,the simulation which the data assimilation for the region of Northwest Pacific is carried out.The comparison between the simulation result with data assimilation and without data assimilation reveals that the data assimilation is capable of improving the simulation results.
