The present paper presents a spectral analysis of the 500-millibar level in the northern hemisphere for a large-scale synoptic variation the result indicates that the wave of wave number 5 plays an important role in the change of circulation. During a breakdown of zonal circulation, the angular-momentum transfer is northward, and accomplished largely by the wave of wave number 5. During the formation of zonal circulation, the transfer of angular momentum is southward and also accomplished largely by the wave of wave No. 5. Author
