    摘要
  • 摘要: 所作的孪生实验表明:通过利用变分优化控制技术将气象学和海洋学(表层和次表层)的观测资料同化到海洋的埃克曼层模型中,可将未知的边界条件(风应力拖曳系数)和垂向涡动黏性系数的分布同时反演出来.
    Abstract: A variational optimal control technique is used to assimilate both meteorological and oceanographic(sea surface current and subsurface current) observations into an oceanic Ekman layer model.An identical twin experiment is discussed.By fitting the model results to the data,the unknown boundary condition(the wind stress drag coefficient) and the unknown vertical eddy viscosity distribution are deduced simultaneously from the data.
