摘　　要：The steady analytical solution of the perturbation equations describing the mesoscale vortex in the atmosphere is obtained. By analyzing the 3D wind field, the 3D spiral structure in physical space for unstable stratification is found. In many respects such as the 3D distribution of pressure and vorticity fields, the mesoscale spiral vortex is very similar to typically real cyclones.
