Mean vertical winds in the mesosphere and thermosphere are extremely difficult to measure because of their expected small values on the order of cm/s. Sophisticated lidar observations in Antarctica have revealed surprising results of the time-mean vertical winds being on the order of m/s. We have been holding off these results for six years, out of the precaution of such results radically different from theoretical expectations of the residual mean (meridional) circulation. Now after many investigations of all possible artifacts and geophysical causes, we are convinced that the lidar-measured results of mean vertical winds are geophysical and represent the real situation in the polar winter middle and upper atmosphere. Therefore, it's time to publish these time-mean vertical winds, which may change our view of the global, regional, or local meridional circulations, impacting future development of general circulation models and transport studies of species, heat, energy, and momentum.
