| Abstract: | Variational data assimilation applied to meteorology and oceanology has shown its advantage in recent ycars. The adjoint method is described in this paper in the following arrangement. Firstly a Lagrange multiplier including the governing equations of oceanic numerical models is introduced in order to explain its mathematical property. Secondly some techniques how to define a cost function is suggested and then the solution procedure is outlined. At last this paper reviews some advances on the involved numerical researches about occanography using the ad joint method. |
