   <abstract xml:lang="ru">
    <p>Проводится сравнительная оценка вклада вихрей и других динамических структур в общую энергетику Лофотенской котловины. Основой исследования являются данные океанического реанализа GLORYS12V1 за 1993–2019 гг. Для области, ограниченной изобатой 3000 м, оценивается общая кинетическая и потенциальная энергия, а также соответствующий вклад в нее вихревой&#13;
энергии. Для анализа применяется метод автоматической идентификации вихрей, позволяющий в выделенных областях получить оценки вихревой кинетической и потенциальной энергии. Установлено, что потенциальная энергия, как циклонов, так и антициклонов, в среднем в 2–3 раза превышает значения кинетической энергии, при этом для антициклонов значения энергии&#13;
доминируют относительно энергии циклонов. Рассматривается межгодовая изменчивость и сезонный ход вихревой кинетической и потенциальной энергии. Сезонный ход выявил повышение обоих типов энергии в зимние месяцы. Установлено, что вклад вихрей в общую энергетику котловины невелик. Доля кинетической энергии вихрей составляет 7,3%, потенциальной энергии –&#13;
8,4%. Это означает, что основной вклад в энергетику котловины дают не мезомасштабные вихри, а другие динамические структуры – филаменты и фоновое течение.</p>

    <p>A comparative assessment of the contribution of eddies and other dynamic structures to the energy of the Lofoten Basin is carried out. The basis of the study is the data of global ocean reanalysis GLORYS12V1 for 1993–2019. We estimate the total kinetic and potential energy as well as the corresponding contribution of eddy energy for a region bounded by an isobath of 3000 m. We use the method of automatic identification of vortices for the analysis which allows us to calculate the eddy kinetic and potential energy in the automatically selected areas of the eddies. We establish that the potential energy of both cyclones and anticyclones is on average 2–3 times higher than the kinetic&#13;
energy values, and the energy values of kinetic and potential for anticyclones dominate relative to the energy of cyclones. We also consider the interannual variability and seasonal course of eddy kinetic and potential energy. The seasonal course revealed an increase in both types of energy in the winter months. It is established that the contribution of eddies to the total energy of the basin is small. The contribution of eddy kinetic energy to the total energy of the basin is 7.3%, and the contribution of eddy potential energy is 8.4%. This means that the main contribution to the energy of the basin is made not by mesoscale eddies, but by other dynamic structures i.e. filaments and background flow.</p>
