It is pointed in this paper that the influence of the component of nongeostrophic windon the potential vorticity transportation in the north-south direction must be considered inthe energy propagations of stationary planetary waves. Then, the wave action conservationequation for planetary waves is demonstrated and the wave action flux, i.e. Eliassen-Palmflux, is obtained in a spherical atmosphere. It is also demonstrated by WKBJ method in this paper that the distribution of E-R fluxvector due to planetary wave is parallel to the local group velocity of waves. Stationary planetary waves responding to an idealized forcing mechanism are computed bymeans of a multi-level model. It is verified by the distributions of E-P flux vector thatthere are two wave guides in the stationary planetary wave propagations in a spherical at-mosphere in winter, i.e. there should be another wave guide pointing from the troposphere atmiddle latitudes toward the upper troposphere at low latitudes in addition to the polar wavegu
