Для минимизации численных шумов использован метод наклонного расчетного домена и регулярная прямоугольная сетка. Исследованы свойства адвективных схем высокого порядка точности. Показана принципиальная возможность явного численного воспроизведения относительно крупных (порядка метра и более) турбулентных структур в океане — конвективных ячеек. Накопление поверенного на физическом эксперименте цифрового массива высокого разрешения 3-мерных полей скорости и трассеров (активного и пассивного) для диапазона чисел Рейнольдса 30–300. В дальнейшем данный массив будет использован для разработки новых параметризаций в крупномасштабную модель циркуляции океана.</p></abstract><trans-abstract xml:lang="en"><p>A detailed non-hydrostatic model of gravitational flow over an inclined bottom is being developed, which is capable of explicitly reproduce convective cells for future generalization and new parameterizations development. To minimize numerical noise, the method of an inclined computational domain and a regular rectangular grid are used. The properties of high-order accurate advection schemes are investigated. The fundamental possibility of explicitly numerical reproduction of relatively large (on the order of a meter or more) ocean turbulent structures, such as convective cells, is demonstrated. A high-resolution digital array of 3-dimensional velocity and tracer fields (active and passive) created based on a physical experiment for a range of Reynolds numbers of 30–300. This array will be used to develop new parameterizations for a large-scale ocean circulation model.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>численная модель</kwd><kwd>моделирование больших вихрей</kwd><kwd>лабораторный бассейн</kwd></kwd-group><kwd-group xml:lang="en"><kwd>numerical model</kwd><kwd>large eddy simulation</kwd><kwd>laboratory tank</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Минобрнауки России для ИО РАН (тема № FMWE-2024-0029).</funding-statement><funding-statement xml:lang="en">The research was carried out within the state assignment of Ministry of Science and Higher Education of the Russian Federation for IO RAS (theme № FMWE-2024-0029)</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">Родионов А.А., Ванкевич Р.Е., Лобанов А.А., Шпилев Н.Н.
