THE CONSTANT ENERGY TUBES OF A LANDING TYPHOON

In this paper, based on isentropic relative-flow analysis, it is found that there are constant energy tubes in typhoon. These constant energy tubes appear also in the severe rainstorms produced by. other synoptic systems, such as the vortices in South-western China and warm shear line. It is pointed out that these constant energy tubes play important role in the summer energy balance of the atmospheric general circulation.
