%X Based on a mathematic model of the dynamic system of the tropical atmospheric motion, the cause of periodic oscillations is attributed to the elliptic condition of phase diagram of the dynamical system. The current research emphasizes the effects of cold and warm air activities from midlatitudes of the Southern and Northern Hemispheres on thermal structure of the atmosphere over tropical area, and explores the effect of those external thermal forcing on the formation of in the periodic oscillations tropical atmosphere.
