Possible connections between the intensity of stratosphere circumpolar vortex (CPV) and variations in the number of sunspots, sector pattern of the interplanetary magnetic field, and other factors of the space weather are considered. The presence of a tight enough connection between long-period variations of CPV intensity as compared to monthly average number of sunspots is shown. Variations with a period of approximately 2 years are found, which can be associated with a quasi-biennial cycle in a dynamic behavior of the equatorial stratosphere.
