Retrospective　Time　Integration　Scheme　in　Numerical　Models

In view of the fact that the atmosphere is capable of memory, this research suggested and developed the viewpoint of atmospheric memorial dynamics. By introducing a memory function into the dynamic-thermodynamic equations of the atmosphere, these equations can be transformed into difference-integral equations. In this way, the numerical solution of the atmospheric motion can be obtained by using several initial fields rather than only one initial field. The retrospective time integration scheme is an original scheme based the system self-memorization principle, which differs greatly from other
