      <abstract xml:lang="ru">
        <p><bold>Цель.</bold> С использованием данных натурных измерений показать, что в заливе Посьета под воздействием сейшевых колебаний его уровня в осенний период в условиях параметрического резонанса возбуждаются внутренние волны (ВВ).</p>
        <p><bold>Методы и результаты.</bold> Методами спектрального анализ установлен ряд частот ВВ, близких к частотам самых интенсивных сейшевых колебаний залива. Для горизонтальной компоненты орбитальной скорости ВВ получено уравнение Матье и выполнен его анализ. Для условий наблюдения ВВ сформулированы необходимое и достаточное условия реализации параметрического резонанса в модельном бассейне, аппроксимирующем залив Посьета. Проверка этих условий показала, что в заливе в осенний период выполнены как необходимое, так и достаточное условия параметрического резонанса между ВВ и сейшевыми колебаниями уровня.</p>
        <p><bold>Выводы.</bold> Экспериментальные данные свидетельствуют о том, что в осенний сезон в заливе Посьета ряд частот ВВ близок к частотам свободных колебаний уровня залива. Показано, что баротропные течения, индуцированные сейшевыми колебаниями, могут возбуждать внутренние волны посредством параметрического резонанса.</p>

        <p><bold>Purpose.</bold> The purpose of the study is to show (using the <italic>in situ</italic> measurement data) that in autumn under parametric resonance conditions, internal waves (IW) are excited in Posyet Bay under the influence of seiche vibrations of its level.</p>
        <p><bold>Methods and Results.</bold> The spectral analysis methods have revealed a number of IW frequencies close to those of the most intensive seiche vibrations of the bay. The Mathieu equation was obtained and analyzed for the horizontal component of IW orbital velocity. For the conditions for observing IW, the necessary and sufficient conditions for implementing the parametric resonance in the model basin approximating Posyet Bay, were formulated. Verification of these conditions has shown that in autumn both necessary and sufficient conditions of the parametric resonance between the IW and sea level seiche vibrations are fulfilled in the bay.</p>
        <p><bold>Conclusions.</bold> The experimental data indicate that in the autumn season a number of IW frequencies are close to those of free oscillations of the sea level in Posyet Bay. It is shown that the barotropic currents induced by seiche vibrations can excite internal waves by means of parametric resonance.</p>
