   <abstract xml:lang="ru">
    <p>В работе проведен совместный анализ пространственно-временной динамики интенсивности ионосферных и стратосферных возмущенний (с масштабами, характерными для внутренних гравитационных волн) на разных долготах средних широт Cеверного полушария. Анализируются зимние периоды 2012–2013 и 2018–2019 гг., когда происходили сильные внезапные стратосферные потепления (ВСП). Показано, что в области существования зимнего циркумполярного вихря в стратосфере происходит увеличение возмущенности в ограниченном широтном интервале 40°–60° N. В условиях ВСП прекращается генерация возмущений в стратосфере, что проявляется в значительном снижении индекса стратосферной возмущенности. Подобную динамику демонстрируют и широтно-временные распределения индекса возмущенности полного электронного содержания ионосферы. Уровень ионосферной возмущенности на средних широтах существенно снижается после ВСП. Уменьшение ионосферной возмущенности можно объяснить уменьшением волновой генерации в стратосфере, связанным с разрушением циркумполярного вихря в периоды ВСП.</p>

    <p>In this work, we perform a joint analysis of the spatial-temporal dynamics of ionospheric and stratospheric variability (with scales characteristic of internal gravity waves) at different longitudes of midlatitudes of the Northern Hemisphere. We analyze the winter periods of 2012–2013 and 2018–2019 when strong midwinter sudden stratospheric warmings (SSWs) occurred. An increase in the variability in the stratosphere is shown to occur in a limited latitude interval 40°–60° N in the region of existence of a winter circumpolar vortex. Under SSW conditions, the generation of wave disturbances in the stratosphere ceases manifesting itself in a significant decrease in the stratospheric variability index. Similar behavior is noted in the spatial-temporal dynamics of the index of the total electron content variability. The level of ionospheric variability at midlatitudes decreases significantly after SSW peaks. The decrease in the ionospheric variability can be explained by a reduction in wave generation in the stratosphere, associated with the destruction of the circumpolar vortex during SSWs</p>
