В численных экспериментах варьировалась как высота ступеньки, так и ширина уступа. Задача решается в рамках полнонелинейной модели гидродинамики невязкой несжимаемой стратифицированной жидкости. Первичный анализ состоял в оценке значений безразмерных параметров, как правило используемых в задачах о накате: числа Фруда, Ирибаррена,  отношения характерной длины волны к характерной ширине склона, отношения топографического уклона к характерному наклону волновых пучков. Поскольку линия «уреза» для нижнего пикноклина частично или полностью находится на ступеньке, можно было бы ожидать динамику, связаную с заплеском, обрушением или отражением волн, распространяющихся по нижнему пикноклину, однако этого не происходит. Показано, что отражение волнового пакета от уступа минимально при всех рассмотренных случаях, наблюдается сильное укручение волны, но при этом обрушения не происходит — волна на нижнем пикноклине при прохождении уступа быстро затухает. Анализ спектральных амплитуд и полей энергии позволяет сделать вывод, что происходит передача энергии с нижнего пикноклина на верхний. Бризер в двухслойной среде не может существовать, но сформировавшийся после его разрушения волновой пакет в верхнем пикноклине обладает значительно большей энергией, чем до уступа.</p></abstract><trans-abstract xml:lang="en"><p>   In this paper, we study the process of transformation of a localized wave packet over a bottom step in a three-layer fluid, in which the height of the step is equal to or exceeds the thickness of the lower layer; therefore, density stratification becomes two-layer in the shallow water zone. In numerical experiments, both the height of the step and the width of the step were varied. The problem is solved in the framework of a fully nonlinear model of hydrodynamics of an inviscid incompressible stratified fluid. The primary analysis consisted in estimating the values of dimensionless parameters used, as a rule, in runup problems: the Froude and Iribarren numbers, the ratio of the characteristic wavelength to the characteristic slope width, the ratio of the topographic slope to the characteristic wave beam angle. Since the “cutoff” line for the lower pycnocline is partially or completely located on a step, one could expect the effects of run-up, breaking or reflection of waves propagating along the lower pycnocline, but this doesn’t happen. It is shown that the reflection of the wave packet from the step is minimal in all cases considered, a strong steepening of the wave is observed, but no breaking occurs in this case — the wave then just quickly decays on the lower pycnocline. An analysis of the spectral amplitudes and energy fields allows us to conclude that there is a transfer of energy from the lower pycnocline to the upper one. The breather in a two-layer fluid cannot exist, but the wave packet formed in the upper pycnocline after its destruction has much higher energy than it has before the step.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>внутренние волны</kwd><kwd>бризер</kwd><kwd>волновой пакет</kwd><kwd>доступная потенциальная энергия</kwd><kwd>полнонелинейная модель гидродинамики</kwd><kwd>трехслойная жидкость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>internal waves</kwd><kwd>breather</kwd><kwd>wave packet</kwd><kwd>available potential energy</kwd><kwd>fully nonlinear hydrodynamic model</kwd><kwd>three-layer fluid</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Представленные результаты получены в рамках государственного задания в сфере научной деятельности (тема № FSWE-2023-0004 «Нелинейная волновая динамика прибрежной зоны в условиях меняющегося климата и антропогенного воздействия») и при поддержке гранта Президента РФ по государственной поддержке ведущих научных школ РФ НШ-70.2022.1.5</funding-statement><funding-statement xml:lang="en">The presented results were obtained within the framework of the state assignment in the sphere of scientific activity (theme No. FSWE-2023-0004 “Nonlinear wave dynamics of the coastal zone under changing climate and anthropogenic impact”) and with the support of the grant of the President of the Russian Federation on the state support of leading scientific schools of the Russian Federation NSh-70.2022.1.5</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">Pineda J.
