Abstract
Mainly, from the analysis of vorticity in the case of the typhoon, it is found that small perturbations superpose upon the circular vortex seemingly uniform at a glance, and that they travel as wave-motions. Furthermore, as an attempt to explain this phenomenon, approximate solutions of the perturbation equation of the circular vortex whose basic currents are gradient winds, are obtained, and this theoretical result is com pared with the analysis.Keywords
