摘要：
Methods for the combined use ofmathematical models and observational data for studying and forecasting the evolution of natural processes in the atmosphere, ocean, and environment are presented. Variational principles for estimation of functionals defined on a set of functions of state, parameters and sources of models of processes are a theoretical background. Mathematical models with allowance for uncertainties are considered as constraints to the class of functions. Attention is focused on methods of successive data assimilation and on inverse problems.
