Abstract: In this paper, solitary Rossby waves in the rotating atmosphere are investigated. It is found that under the condition of one meridional wave, the stationary solitary Rossby wave has dipole structure with tile anticyclone north of the cyclone, and the stronger the rotational basic flow, the stronger the stationary dipole structure, more over, in the high latitude region, the dipole structure is also stronger, this shows that the local dipole structures obtained here can explain why the persistent dipole blocking usually occurs in the high latitude regions.
