Abstract

The tropopause is an important object of the circulation regime of the upper atmosphere, the temperature and wind characteristics of which can affect the processes in the middle and lower troposphere. Jet streams often pass near the tropopause level, which affect the transport and propagation of atmospheric pollutants. The paper analyzes the seasonal features of the wind regime at the tropopause level in the southern regions of Irkutsk region. It was revealed that the observed climate changes in Irkutsk region are closely consistent with changes in the meridionality of flows and wind speed at altitudes. The increase in the contribution of the southern winds during the warm season should be considered when assessing the ecological state of the region, especially during periods of dust storms in Mongolia and China.
