N2 - The latitudinal and seasonal dependences of vertical profiles of the averaged vertical wind for different time intervals from 1992 to 2006 based on the data of the UKMO atmosphere general circulation model are 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 mu m) aerosol particles with a density up to 1.0-1.5 g/cm(3) 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 fields of vertical wind supposes the opportunity of formation of dynamically stable aerosol layers in the middle stratosphere.
