High-Resolution Modeling of the M₂ Internal Tide in the Ice-Free East Siberian Sea: Dynamics and Energetics

Using the high-resolution version of the QUODDY-4 3D finite-element hydrostatic model, the fields of the dynamic characteristics (amplitudes of tidal elevations and ellipses of the baroclinic tidal velocities) at the pycnocline depth and the average (over a tidal cycle) depth-integrated components of the baroclinic tidal energy budget in the ice-free East Siberian Sea are presented. These include the density, the advective transport and horizontal wave flux of baroclinic tidal energy, the mutual conversion rate of tidal energy, and the dissipation rate of baroclinic tidal energy due to bottom friction. On average (over a tidal cycle and the sea area), their values were equal to \(1.7 \times {{10}^{3}}\)  J/m², 11 and 269 W/m, and \(1.65 \times {{10}^{{ - 3}}}\) , \(1.1 \times {{10}^{{ - 3}}}\)  W/m², respectively. These values are in general smaller than their analogs in the Laptev Sea.
