Deducing the wind stress drag coefficient and the oceanic eddy viscosity profile by data assimilation

  • Received Date: 1999-07-25
  • Rev Recd Date: 2000-02-25
  • 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.
