Rocket vapor trail measurements of the properties of the high latitude wind system are compared with Ogo 6 measurements, the atomic densities being studied as a function of geomagnetic local time at three seasons for three ranges of magnetic activity. It is found that the atomic oxygen densities at altitudes in the region of 120 km are about 35% lower in the post-midnight sector than in the afternoon and evening sectors, decrease with increasing magnetic activity, and are lower in summer than in winter. The variations are related to vertical velocities in the 95-150 km altitude range and to the meridional fluxes at 70 deg geomagnetic latitude. The upward average vertical velocity of atomic oxygen in the region poleward of 70 deg is calculated to be of the order of 0.3 m/s at 120 km and the energy transported by the winds out of this region is calculated to be of the order of 10 to the 10th W for Kp levels of 2.
