The finite-difference model of the atmospherical dynamics with the conservation laws

A description of the basic model of atmosphere, which has been worked out in Siberian Scientific Hydrometeorological Institute and Computing Center of Siberian Division of Russian Academy of Sciences, is presented in this paper. Some concervations laws of the model allow to realize long-time integration. A limited-area variant of the model served as a basis of operative technology of regional weather prediction for Siberia. The results of predictions with this model are described at the end of this paper.
