PECULIARITIES OF INERTIAL AND TIDAL OSCIL LATIONS OF CURRENT VELOCITYAND TEMPERATURE IN MEGAPOLYGON EXPERIMENT

Inertial and tidal oscillations of current velocity and temperature in the Ocean and their connection with mean current and mean temperature changes are analyzed on Megapolygon experiment data in the sub-arctic frontal zone in the North-West Pacific. The oscillations have unusual features, partly created by distortions. Current meter displacements caused by surface waves and temperature horizontal gradient are the so urces; of distortions. Nevertheless and tidal inertial waves intensifi cation are revealed near fronts and intrathermocline lenses. It is lik ely that intensification is caused by wave-current interaction.
