%X Based on the analyses of the mesoscale disturbing structure of the 1992 Hurricane Andrew with the high resolution output of numerical model, the authors make dynamic analyses of the slantwise updraft in the eyewall, and point out that there is one kind of developing mechanism-nonlinear convective and symmetrical instability. Last, the paper documents that the gradient unbalance is the physical ground of CSI in vortex atmosphere, and diagnoses the possibility of this kind of developing mechanism in the slantwise updraft.
