В рамках численной модели, основанной на обобщенном уравнении Гарднера, зарегистрированная в 1998 г. форма внутреннего бора использована в качестве граничного условия, что позволило дать возможный прогноз ее эволюции. Исследовано влияние изменчивости гидрологии и влияния диссипации в придонном пограничном слое и горизонтальной диффузии на прогнозируемые характеристики внутренних волн. Показано, что хотя характеристики внутренних волн чувствительны к этим факторам, тем не менее, резкий перепад в глубине залегания термоклина (бор) сохраняется на одном—двух километрах от места регистрации, а затем он трансформируется в солибор (ударная волна с ондуляциями). В рамках модели Гарднера исследован также собственно процесс возникновения бора из цуга внутренних волн в результате дисперсионного фокусирования. </p></abstract><trans-abstract xml:lang="en"><p>The numerical modeling of dynamics of the internal bore is done for the area in the Pechora Sea where the internal bore had been observed. The bore record obtained in 1998 is used as initial condition for numerical model based on the Gardner equation and analysis of bore evolution is done. The influences of hydrology variations and wave dissipation in the bottom boundary layer as well as the horizontal diffusion on the forecasted wave shape have been studied. It is shown that although internal wave characteristics are responsive to these factors nevertheless the abrupt overfall of isotherms in the thermocline (internal bore) is saved in one-two kilometers from the point of observation, and after that it is transformed into solibore (shock wave with ondulations). The process of internal bore generation from the train of nonlinear internal waves is studied as the result of the dispersive focusing. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>внутренние волны</kwd><kwd>солибор</kwd><kwd>обобщенное уравнение Гарднера</kwd><kwd>диссипация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>internal wave</kwd><kwd>solibore</kwd><kwd>variable-coefficient Gardner equation</kwd><kwd>dissipation</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Представленные результаты получены в рамках выполнения государственного задания в сфере научной деятельности (Задание № 2014/133 («организация проведения научных исследований») и Задание № 5.30.2014/K).</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">Holloway P.
