A discrete assimilation system for a one-dimensional variable coefficient convection–diffusion equation is constructed. The variational adjoint method combined with the regularization technique is employed to retrieve the initial condition and diffusion coefficient with the aid of a set of simulated observations. Several numerical experiments are performed: (a) retrieving both the initial condition...
As a kind of promising and potential data assimilation technique to which various countries' meteorologists had attached great importance, the variational data assimilation had so far become the main development direction in meteorological data assimilation. So this paper is limited to illustrate the main idea of the variational adjoint method by constructing the variational adjoint system which here...
