This paper contains estimations of the spatial variability of the kinetic energy density in semidiurnal tidal waves of the lowest baroclinic mode in the North Equatorial Countercurrent region. We have noted an essential reduction in the energetic density of semi-diurnal waves at the north boundary of the North Equatorial Countercurrent and a build-up of energy in short-period internal waves. The hydrodynamic instability of baroclinic tidal waves may be regarded as the mechanism responsible for the frequency energy redistribution.Translated by Vladimir A. Puchkin. 相似文献

Conditions for generating a train of intensive internal waves and a solitary internal wave, as well as the evolution and dissipation
of shelf waves have been studied using temperature measurements at six buoy moorings and an array of distributed temperature
meters towed in the Morocco shelf zone. Waves of each type have been numerically simulated. The paper's focus is the generation
of a baroclinic tide in a shelf zone and the occurrence of a packet of intensive internal waves on the back slope of a baroclinic
wave. Besides, it studies the mechanism responsible for the generation of a solitary internal wave of soliton type. Thein situ data and the model data are matched up and shown to be consistent, in terms of quality and quantity.

This paper reports empirical data on short-period internal waves in the Black Sea and Aegean frontal zones, collected through the use of distributed temperature sensor arrays. Peculiar features of the behaviour and propagation of the internal waves in these zones are shown. It is shown that the wavefield is anisotropic and reduction of the wave lengths diminishes during the climb up a sloping pycnocline. The energy level of the spectra of internal wave oscillations in the frontal zones of non-tidal seas was found to be lower than that relating to oceanic frontal zones.Translated by Vladimir A.

The measurements data provided by an antenna of distributed temperature sensors, mounted on an oceanographic tower in the
South Crimea continental shelf area, were applied to study the mechanism for the generation of short-period internal waves
with anomalous amplitudes in the Black Sea. For analysis, information was incorporated concerning the background hydrological
and meteorological conditions that were observed during the experiment. A mathematical model for the phenomenon under study
has been constructed, and calculations of the anomalous internal wave generation have been presented. The paper contains a
comparative analysis of thein situ data and simulation results, and demonstrates a good qualitative/quantitative agreement between the parameters of internal
waves.

The data accumulated by a measuring complex equipped with a gradient-distributed temperature sensor in the course of towing in the shelf zone near the South Coast of the Crimea and in the region where the flow of the Rim Current crosses the shelf edge are used to analyze the energy and space characteristics of internal waves formed when the flow runs through the shelf edge and to study the process of their propagation both to the coast and to the open part of the sea. 相似文献
