Abstract: The data of U, V, T and Z on seven Layers (i. e. , 1000, 850, 700, 500, 300, 200 and 100hPa) from Dec. 1st, 1981 to Feb. 28th, 1982 were chosen for analyzing in this paper. The mean values of these elements in the region near equator (5°S-5°N, 80-120°E) and in the region of middle latitude (40-60°N, 140-160°E) were taken to be objects for research and then the feature of evolution in time of various terms in the kinetic energy equilbrium equation, the feature in vertical distribution of seasonal average and the probable relation between various terms of equation and change of kinetic energy, all of them were analyzed in the research. It showed that the maintenance of kinetic energy of 30-50 days disturbance related mainly to the advection influence and barotropical action of mean flow, but the directions of transfer in equator and middle latitude were reverse. The results also showed that the equator region was the disturbance source, energy was obtained from basic flow and that the response time for influnce of various terms was 2-3 days. But the middle latitude was the disturbance sink, where the energy in basic flow was consumed. The response time for various terms was 5-7 days.
