Abstract: In this article the influence of winter hemispheric circulation on the tropical cyclone and rainfall in summer hemisphere are investigated with special reference to the short range climatic change. It is found that the change of fxequency of tropical cyclone on Atlantic, Western Pacific and Tndian oceans is clealy related to the intensity of anticyclone in the southern hemisphere. On the other hand the change of frequences of tropical cyclone on the southern hemisphere is associated with the strength of the cold air in northern hemisphere. A relationship exists between the rainfall in the summer hemisphere and the circulation in the winter hemisphere. The droughts and floods ovex China are closely correlated with Australian high pressure, and the rainfall over Indonesia and Australia seems to be linked with the activity of Siberia high pressure. It is deduced that in the interactions between hemispheres, winter hemisphere often play a active part, thus it exerts a deep influence on the climate in the summer hemisphere especially with respect to the short range climatic change. It shows that the interactions between both hemispheric circulations and climate is most active in Eastern Asia.
