文档介绍：渤黄东海三维海流场、温度场数值模拟
摘要
本文首先对渤黄东海的环流特征和研究现状作一个简要回顾,接着对POM数值模式作了介绍。本文的第三部分在POM模式的基础上,利用NASA高分辨率的卫星遥感资料SST,采用Nudging同化模拟渤黄东海的三维温度场,减小用热通量做上边界条件所带来的误差。结果表明,模拟的海流场能较好地反映渤、黄、东海的冬季和夏季的环流特征。数据同化后的温度场优于未经同化的温度场。,,,,,。尽管只同化了海表温度,但数据同化对三维温度场结构都有影响。夏季模拟和同化的混合层厚度均偏浅,小于现场观测的混合层厚度。关键词:海流场:温度场;数值模拟:同化;POM模式
Numerical simulation of three—dimensional current field and
temperature field of the Bohai Sea,the Yellow Sea
and the East China Sea
A brief review of the circulation feamr%,the history and the current research situation of the Bohai Sea,the Yellow Sea and the East China Sea is made firstly in this article,Then the POM numerical model is introduced,In the third part of this paper,the Nudging assimilation is used to simulate the three—dimensional temperature field of the Bohai Sea,the Yellow Sea and the East China Sea to reduce the error ofusing heat flux as the upper boundary condition with the use of the high resolution satellite remote sensing data SST on the basis of result shows that the simulated current field carl reflect the circulation characteristics of the Bohai Yellow Sea and the East China Sea temperature field after data assimilation is better than that
without data RMS between the assimilation data and the observed
data of the three stations selected are ,, the RMS between the temperature simulated by heat flux and the observed data are ,O。8792, assimilation affectsthethree dimensional
temperature field although we only assimilate the sea surface mixing
layer depth simulated and assimilated are both shallower than the mixing layer depth observed in situ.
