   <abstract xml:lang="ru">
    <p>The paper examines the variation in the stratospheric polar vortex (SPV) area and the high-latitude stratosphere temperature from November to March for the winter periods 2022–2023 and 2023–2024 against the background of average long-term values of these parameters from 1979 to 2024. In 2022–2023, the SPV area significantly exceeded the climatic values in January and December, and a decrease in the SPV area occurred a month later than the climatic norm. This was accompanied by extremely low temperatures in the polar stratosphere in the first half of winter and a record-breaking “hot” sudden stratospheric warming (SSW) in the second half of winter. In the winter period 2023–2024, no extreme SPV and temperature values were observed, but four SSW episodes were recorded during the winter period, three of which were major. We analyze SPV areas, temperatures in the stratosphere, activity of planetary waves, and discuss the reasons for the differences between the two winter seasons in terms of wave activity.</p>
