A marked seasonal variation of the poleward angular‐momentum flux for the northern hemisphere in the vicinity of 30°N. latitude is obtained from an analysis of upper‐wind soundings for a period of one year. The angular‐momentum flux appears to be about twice as great during the winter as during the summer. Indications of a mean meridional circulation of the strength and character necessary to provide a substantial flux of angular momentum are lacking. It is suggested that the horizontal eddy flux of angular momentum across 30°N. latitude is sufficient to account for the drain of this momentum in middle latitudes.
