Abstract
Vortex motions in the atmosphere are shown to be closely connected with dynamics of the dust nano‐ and microscale particles. The mechanism by which nano‐ and microscale particles are transported from the troposphere into the lower stratosphere by synoptic‐scale vortices, simulated by the soliton solutions to the Charney‐Obukhov equations (Rossby vortices), is described. Redistribution of dust particles in the ionosphere as a result of vortical motions is discussed. It is shown that excitation of acoustic‐gravitational vortices at altitudes of 110–130 km as a result of development of acoustic‐gravitational wave instability, associated with nonzero balance of heat fluxes, owing to solar radiation, water vapors condensation, infrared emission of the atmosphere, and thermal conductivity, leads to a substantial transportation of dust particles and their mixing at altitudes of 110–120 km. One of the ways of transportation of dust particles in the ionosphere is shown to be vertical flows (streamers), which are generated by dust vortices as a result of development of parametric instability.
