Установлено, что поле изоамплитуд и изофаз приливных колебаний уровня очень напоминает то, которое возникает при интерференции встречных волн Пуанкаре в южной части моря и подобных же волн Кельвина в восточной. Это поле содержит 3 реальные амфидромии левого вращения в первой из них и еще 2 во второй. Перечисленные значения параметров приливных колебаний уровня, а также эллипсов баротропной скорости полусуточного приливного течения в отдельных пунктах открытого моря неплохо согласуются с данными in situ изменений. По результатам моделирования определены средние (за приливный цикл) значения плотности баротропной приливной энергии, адвективного переноса кинетической баротропной приливной энергии, горизонтального волнового потока потенциальной баротропной приливной энергии и скорости диссипации баротропной приливной энергии. Получена оценка времени диссипации баротропной приливной энергии. Ее сравнение с аналогичной оценкой для Мирового океана в целом убеждает, что море Лаптевых является одним из значимых стоков баротропной приливной энергии в Мировом океане.</p></abstract><trans-abstract xml:lang="en"><p>The results of high-resolving modeling for the surface semidiurnal tide M2 in the Laptev Sea have been discussed. They are obtained using a high-resolving version of 3D finite-element hydrostatic model QUODDY-4. It is established that the field of isoamplitudes and isophases of tidal elevations closely resembles that incidents to the interference of counter-coming Poincare waves in the southern part of the Sea and similar Kelvin waves in the eastern one. The above field contains 3 real left-rotating amphidromes placed in the first of them and 2 in the second one. The model amplitudes and phases of tidal elevations, maximum and minimum barotropic tidal velocitites, and the direction of rotation of the barotropic tidal velocity are in reasonably good agreement with the available data of in situ measurements. The modeling results are also used to determine the averaged (over a tidal cycle) density of barotropic tidal energy, the advective transport of kinetic barotropic tidal energy, the barotropic horizontal wave flux of potential tidal energy, and the dissipation rate of barotropic tidal energy in the Sea. An estimate for the dissipation time is found. Its comparison with the existing estimate for the World Ocean as a whole shows that the Laptev Sea is one of significant sinks of barotropic tidal energy in the World Ocean.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>динамика и энергетика приливов</kwd><kwd>высокоразрешающее моделирование</kwd><kwd>бюджет баротропной приливной энергии</kwd><kwd>море Лаптевых</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dynamics and energetics of tides</kwd><kwd>high-resolving modeling</kwd><kwd>barotropic tidal energy budget</kwd><kwd>the Laptev Sea</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания (тема 0149-2019-0015).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Добровольский А.Д., Залогин Б.С.
