摘要：

Two main problems in the numerical weather prediction are how to improve the computational precision of schemes and how to save the CPU time for integrations. In this note, the splitting method, which is applied to the difference schemes of explicit and complete square conservation, is described according to the separability of the adjustment stage (the fast process) and the advection stage (the slow process) in atmospheric motion.
