Abstract
This contribution is focused on the semidiurnal internal tide in the Barents Sea generated north of the critical latitude (74.5° N). The study is based on the numerical modeling of internal wave generation and dynamics using of the Euler 2D equations for incompressible stratified fluid. The study site is located between Svalbard and the Franz-Victoria Trough. A Section 350 km long is chosen for the analysis in this basin. The bottom topography in the region is quite steep; four underwater hills with heights about 150–230 m over the background depth of about 350 m are located here. Calculations confirm the observation data in the vicinity of this region. Intense nonlinear internal waves with amplitudes up to 50 m and lengths of about 6–12 km are generated in this region of the Arctic.
