| Abstract: | On the basis of synoptic analysis, the terms of synoptic and subsynoptic scale kinetic energy and the nonliner kinetic energy interaction terms were calculated, respectively, in order to analyze the main dynamical process of interactions between their kinetic energies of synoptic and subsynoptic scale systems in the precipition process. The results show that the kinetic energy interactions between synoptic and subsynoptic scales exist in the torrential rain system, and the motion of subsynoptic scales increases kinetic energy of synoptic scale, and so as to support the torrential rain system. |
