Abstract

Abstract

Taking the tropical cyclone(TC) as a circular vortex with radius R,horizontal motion equations are averaged over the whole TC area to get its movement with non-friction,weak-environment.Then,weobtain it's analytical resolution,and discuss the influence of the TC structure(include axial symmetry and asymmetry) on movement.The results show that TC moves flutter periodicity with sinuso idalorcosine by the influence of TC structure, and the mobile direction changes abruptly at completeperiod and semi-period.The asymmetrical structure with wave number 2,and more than,can create the extramovement,but can't with wave number 1.
