Целью настоящей работы был анализ сезонных изменений концентраций приземного озона (ПО), изучение случаев превышения предельно допустимых концентраций (ПДК), эпизодов экстремально высоких концентраций (ЭВКО) и ночных повышений содержания озона (НПСО) для предложения механизмов описанных явлений и эффективных стратегий достижения установленных нормативов. В ходе работы были изучены концентрации приземного озона и его предиктов на посту государственного мониторинга состояния атмосферного воздуха в течение 2019–2021 гг. в городе Челябинске. Согласно результатам исследований, было выявлено, что концентрация ПО на территории города Челябинска начинает увеличиваться в марте и остается высокой в течение лета. Концентрация ПО складывается из нескольких составляющих: (1) поступающего из нижней стратосферы и верхних слоев тропосферы в результате стратосферных вторжений (СВ), которые увеличиваются в летний период; (2) фотохимически образующегося с максимумом в июне, при этом рассчитанное на основании данных наземного мониторинга соотношения HCHO/NOх не может быть использовано в качестве надежного индикатора режима образования ПО; и (3) поступающего с низкоуровневыми мезоструйными течениями (НУМСТ), частота возникновения которых увеличивается в ночной период весной и летом, о чем свидетельствует высокая повторяемость НПСО.

The aim of this work was to analyse seasonal changes of surface ozone concentrations (SO), to study cases of exceeding maximum permissible concentrations (MPC), extreme ozone episodes (EOEs) and nocturnal ozone enhancement (NOE) in order to propose mechanisms for the phenomena described and effective strategies for achieving established standards. In the course of the work, the concentrations of SO and its predicates were studied at the state air monitoring station in the city of Chelyabinsk during 2019–2021. According to the research results, it was revealed that the SO concentration in the Chelyabinsk urban area begins to increase in March and remains high during the summer. The SO concentration consists of several components: (1) that transported from the lower stratosphere and the upper layers of the troposphere as a result of stratospheric invasions (SI), which increase in summer; (2) that formed photochemically with a maximum in June: while the HCHO/NOx ratio calculated on the basis of ground‐based monitoring data cannot be used as a reliable indicator of SO formation; and (3) that incoming with low‐level jets (LLJs), the frequency of which increases during the night in spring and summer, as evidenced by the high frequency of NOE.
