Transport properties of secondary vortex structures developed in the range of the upper mesosphere-lower thermosphere are considered. The development of the vortex structures with many scales in the lower ionosphere can result in intensive thermal and mass transfer. These processes can influence considerably the recirculation of the metallic ions and atoms accumulated just at the same altitude range by thermal tides.

Keywords: mesosphere, lower thermosphere, Ekman-type instability, vortex structures, transport of metallic ions and atoms
