The conservation of wave action has been derived with WKB method when the back-ground flow of the eddy is symmetric for axis in a stratified rotative fluid. The necessarycondition of the turbulent evolution in the eddy has been obtained from this conservation.The necessary condition is that the tangent phase velocity of turbulent eddy is equal to therotative angular velocity of the basic flow, or that there is a common revelve circle some-where in the eddy. According to the principle mentioned above the generative and growing condition of thehurricane has been analysed. It has been shown from real data that the vertical circulationin the hurricane may have double circles, from which a possible explanation about the exist-ence of hurricane eye has been given.
