The mean meridional circulation in the stratosphere of the northern hemisphere is determined from IGY data available for a network of approximately 240 stations during the period July 1957-June 1958. Zonal averages for every 5 deg latitude from the equitor to 80 deg N are presented. The yearly average suggests at 100 mb a three cell pattern with poleward motion north of 55 deg N, equatorial motion from 15 deg to 55 deg N, and weak poleward motion from the equator to 15 N. At higher levels eqluatorward motions are observed in middle and low latitudes. The highest meridional velocity of +60 cm/sec is obseived at 70 deg N at the 100 mb level. These averages are compared with similar results for the southern hemisphere. Vertical velocities, computed adiabatically at 75 and 40 mb, made it possible to estimate the contribution of the diabatic heating to the horizontal meridional velocities at 50 mb, and also to give an estimate of the diabatic heating itself.
