Спектральные модели рассчитывают эволюцию распределения потенциальной энергии по углу и частоте, но не содержат информации о геометрии и статистических характеристиках волн. Эти сведения приходится извлекать с помощью дополнительных гипотез, не всегда хорошо обоснованных. Предлагается вычислительная процедура, позволяющая трансформировать спектральную информацию в двухмерное волновое поле. Такое поле состоит из совокупности линейных мод со случайно распределёнными фазами. Это поле нереально, поскольку оно не обладает нелинейными свойствами: повышенной вероятностью крупных волн и различными свойствами асимметрии, например, повышенным эксцессом. На следующем этапе разработанной процедуры предлагается принимать воспроизведённое на основе спектра линейное волновое поле как начальное условие для фазо-разрешающей модели. Затруднение состоит в том, что точные модели, формально пригодные для такого счёта, слишком громоздки и неэффективны, что практически исключает их систематическое применение. Положение может быть исправлено привлечением нового типа моделирования трёхмерных волн, основанного на двухмерных уравнениях. Двухмерная модель считает в десятки раз быстрее, чем точная трёхмерная модель. Анализ результатов, полученных с такой моделью, показал, что она воспроизводит статистические характеристики волн, практически не отличающиеся от результатов точного моделирования. В статье описана процедура обработки спектральных данных и приведены примеры использования разработанного метода процедуры для интерпретации спектрального прогноза волн в Балтийском море.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents an interpretation of the results of spectral wave-forecast model using the phase-resolving model. Spectral models provide the information on the evolution of the potential energy distribution in terms of angle and frequency though the information about the geometry and statistical wave characteristics in such models are not available. This information has to be extracted through the additional, often unsubstantiated, hypotheses. The proposed computational procedure transforms spectral information into a two-dimensional wave field which consists of a set of linear modes with randomly distributed phases is proposed. The wave field is not realistic since it does not have non-linear properties, for example, various asymmetry properties such as increased kurtosis. Afterwards the linear wave field reproduced on the basis of the wave spectrum is set as the initial condition for the exact phase-resolving model. The exact models formally suitable for such calculations are cumbersome and inefficient and that practically restricts their broad and regular application. This restriction can be overcome by using a new type of 3D wave simulation based on 2D equations. The 2D model reproduces the statistical characteristics of the wave field similar to the results of the 3D exact model and runs several times faster. The examples of using the developed method of interpretation of the spectral wave forecast in the Baltic Sea are demonstrated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>трехмерные волны</kwd><kwd>волновой спектр</kwd><kwd>спектральное моделирование</kwd><kwd>фазо-разрешающее моделирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>three-dimensional waves</kwd><kwd>wave spectrum</kwd><kwd>spectral modeling</kwd><kwd>phase-resolving modeling</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа проводилась при поддержке Российского Научного Фонда (проект № 22-21-00139).</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The research was supported by Russian Science Foundation RSF (project No. 22-21-00139).</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">Tolman H.L.
