The method for representing hemispheric atmospheric flow patterns in terms of surface spherical harmonics is discussed. Spectral form of linear balance equation is derived and solved with a suitable boundary condition. The results show that the planetary scale atmospheric systems can be represented to a high degree of accuracy by a limited number of spherical harmonics. The stream function spectrum arrived at by solving spectral form of linear balance equation gives proper representation of actual atmospheric systems.
