Based on the discussion of the balanced, quasi-balanced and non-balanced dynamic characteristics in hurricanes life cycle, a potential vorticity (PV)-ω inversion sys tem is applied to analyze the TC Bonnie(1998), which exhibited the characteristics of asymmetry and steady intensity state.The results show that the basic vortex can be well described by the balanced flows derived through the PV and nonlinear balanced (NLB) equations, whereas by adding the quasi-balanced ω equation, the quasi-balanced flows can reflect the structure of convergent inflow in planetary boundary layer (PBL), divergent outflow in upper troposphere, strong slantwise updraft in eyewall and subsidence motion in hurricane eye.
