The latitudinal and seasonal dependence of vertical profiles of the vertical wind averaged for different time intervals from 1992 to 2006 based on the data of the UKMO general circulation model is analyzed. It is shown that monthly average amplitudes of the vertical wind are approximately ±5 mm/s, while annual average ones are ±1 mm/s. The upward wind can provide the vertical lifting against gravity for sufficiently large (up to 3-5 μm) aerosol particles with a density up to 1.0-1.5 g/cm3 at stratospheric and mesospheric altitudes. The vertical wind probably is a substantial factor of particle motion up to altitudes of 30-40 km and can change essentially the sedimentation rate and the residence time of stratospheric aerosols. The structure of the averaged field of the vertical wind leaves room for formation of dynamically stable aerosol layers in the middle stratosphere.
