摘要：

Based on a certain analogy between the physical conditions in the region of the upper atmosphere, transitional from the mesosphere to the lower thermosphere (MLT), and the atmospheric boundary layer (ABL), for the first time for the upper atmosphere we obtained helicity estimates and analyzed the Ekmantype instability. The performed calculations of the orientation of the formed periodic structures agree with the experimental data.
