A method is described for determining the characteristics of turbulence zones in the upper troposphere based on the processing of measurement data of the SEVIRI radiometer of second-generation European geostationary meteorological satellites in a 6.2 μm water vapor channel. Their spatial and temporal variability in the time interval 2007–2018 is considered. A significant (by 130–60 %) increase in areas occupied by relatively weak and moderate turbulence and a decrease (by 6–33 %) in areas with strong and very strong turbulence were revealed. The relationship of turbulence zones with the characteristics of jet stream and the temperature of the troposphere is investigated. Significant with a probability of more than 95 % annual variations of area of turbulence zones and most of the characteristics of jet stream have been identified. The most pronounced are in phase annual variations of the turbulence areas with the jet stream area and the velocity gradient and counterphase variations with the latitude and longitude of the centre of the jet stream. The connection between the variability of turbulence and the temperature variability of the upper troposphere is revealed. In this case, the effect of temperature on turbulence manifests itself indirectly through the characteristics of jet stream.
