В основе последнего лежит использование скорректированного коэффициента вертикальной турбулентной диффузии, представляющего собой сумму того же нескорректированного коэффициента и коэффициента диапикнической диффузии. Первый из них характеризует влияние неприливных факторов, рассчитываемый с помощью 2,5-уровневой схемы турбулентного замыкания, второй, определяемый отношением индуцируемой внутренними приливными волнами диссипации бароклинной приливной энергии к квадрату частоты плавучести, — влияние чисто приливного фактора. Оценка этой диссипации находится из решения вспомогательной задачи о динамике и энергетике внутренних приливных волн. Обсуждаются поля температуры и солёности морской воды в поверхностном и придонном слоях моря и их вертикальные распределения вдоль меридионального разреза 120в.д. Кроме названных полей и вертикальных распределений, отвечающих сильному восстановлению предсказываемых характеристик к их климатическим значениям, дополнительно выполняются ещё два численных эксперимента для умеренного и смешанного восстановлений. В результате выясняется, что температура и солёность морской воды слабо чувствительны к изменениям их времени восстановления. Сказанное следует из сравнения модельных средних (за выбранный период и по площади моря) значений температуры и солёности морской воды и их вертикальных профилей, рассчитанных при разных значениях времени восстановления. </p></abstract><trans-abstract xml:lang="en"><p>In order to study sensitivity of seawater temperature and salinity in the no-ice Laptev Sea to their restoring times, appending in the boundary conditions for these variables at the free surface, the 3D finite-element hydrostatic model QUODDY-4 and the indirect means of describing internal tidal waves have been applied. The latter is based on the use of the corrected eddy diffusivity representing the sum of the same uncorrected diffusivity and the diapycnal diffusivity. The first of them characterizes the influence of non-tidal factors, computed using 2.5-level eddy closure scheme, the second, determined by the ratio of internal tidal waves induced baroclinic tidal energy dissipation to the buoyancy frequency in square, the influence of purely tidal factor. The estimate of this dissipation obtained from a solution of auxiliary problem on the internal tidal waves dynamics and energetics is attached. Seawater temperature and salinity in the subsurface and near-bottom layers of the Sea and also their vertical distributions along the 120E meridional transection obtained for the strong, moderate, and mixed restoring times are discussed. As a result, it is clarified that seawater temperature and salinity are weakly sensitive to changes in the restoring time. The saying follows from a comparison of model averaged (over a chosen period and by the Sea area) values of seawater temperature and salinity, and from their local vertical profiles, computed with regard to accepted estimates of the restoring time.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>чувствительность</kwd><kwd>моделирование</kwd><kwd>внутренние приливные волны</kwd><kwd>индуцируемая ВПВ диссипация бароклинной приливной энергии</kwd><kwd>время восстановления</kwd><kwd>море Лаптевых</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sensitivity</kwd><kwd>modeling</kwd><kwd>internal tidal waves (ITW)</kwd><kwd>ITW-induced baroclinic tidal energy dissipation</kwd><kwd>restoring time</kwd><kwd>the Laptev Sea</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания (тема № FMWE-2021–0014).</funding-statement><funding-statement xml:lang="en">The work was carried out within the framework of the State assignment No. FMWE-2021–0014.</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">Large W.G., Danabasoglu G., Doney S.C., McWilliams J.C.
