Показано, что обусловленная сезонным циклом морского льда изменчивость гармонических постоянных приливной волны М2 в Центральной и Канадской Арктике меньше средней квадратической ошибки расчета приливных колебаний уровня, так что ее в первом приближении можно не учитывать. Иное дело – окраинные моря Сибирского континентального шельфа, где сезонные изменения амплитуд приливных колебаний уровня могут составлять ± 5 см, фаз – от 15º до нескольких десятков градусов.</p></abstract><trans-abstract xml:lang="en"><p>The results for three-dimensional (3D) winter and summer tidal flows in the Arctic Ocean are presented. It is shown that dependent on ice seasonal variability of the tidal constants (amplitudes and phases of tidal sea surface level elevations) in the Central and Canadian parts of the Arctic Ocean is less than the mean square error in the predicted tidal sea surface level elevations. This means that the seasonal variability can be neglected, at least as a first approximation. A different situation is encountered in the Siberian continental shelf, where seasonal changes of tidal amplitude are ± 5 cm, while those of tidal phase vary from 15º to several tens of degrees.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>приливы</kwd><kwd>сезонная изменчивость</kwd><kwd>моделирование</kwd><kwd>Северный Ледовитый океан</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tides</kwd><kwd>seasonal variability</kwd><kwd>modeling</kwd><kwd>the Arctic Ocean</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Kowalik Z.
