Используется математическая модель циркуляции Балтийского моря, разработанная в ИВМ РАН. Для аппроксимации по времени применяется метод расщепления. Метод разделения области рассмотрен на примере задачи конвекции-диффузии. Использование данного метода разделения области на многопроцессорных вычислительных системах позволяет создавать параллельные алгоритмы.</p></abstract><trans-abstract xml:lang="en"><p>Domain decomposition method based on adjoint equation and inverse problem theory is discussed. The mathematical model of the Baltic Sea circulation, developed in INM RAS, is considered. The splitting method is used for time approximations. Domain decomposition method is studied to convection-diffusion problem. Also using domain decomposition method on multiprocessor computer system is possible to create algorithms for the parallel calculations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>метод разделения области</kwd><kwd>обратные задачи</kwd><kwd>численные методы</kwd><kwd>сопряженные уравнения</kwd><kwd>параллельные алгоритмы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>domain decomposition method</kwd><kwd>inverse problems</kwd><kwd>numerical methods</kwd><kwd>adjoint equations</kwd><kwd>parallel algorithms</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке РНФ (грант 14-11-00609, в рамках которого проведены численные эксперименты) и РФФИ (грант 16-01-00548, в рамках которого проведено исследование сформулированных задач).</funding-statement><funding-statement xml:lang="en">The research is done with the financial support from the RSF (Grant 14-11-00609, within which the numerical experiments were carried out) and the RFBR (grant 16-01-00548, within which the research of the formulated tasks was carried out).</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">Lebedev V.I.
