THE RESULTS OF NUMERICAL SIMULATIONS OF STORM SURGES IN THE WHITE SEA
Abstract
The results of numerical simulations of storm surges in the White Sea using the ADCIRC hydrodynamic model adapted to the conditions of the water body are discussed. Numerical experiments were performed on an unstructured high-resolution grid. The model was verified through the comparative analysis of numerical results and observational data at the Severodvinsk, Solovki and Sosnovets stations. The spatial structure of surges and their propagation features are described. Numerical experiments have shown that the ADCIRC model adequately reproduces residual sea level (RSL) oscillations during surges. This is confirmed by significant correlation between RSL oscillation values obtained by processing of the observational data and from numerical simulations. The RMSE of
model calculations is also relatively small (9–21 cm). The numerical simulations revealed that when cyclones pass, a strong RSL increase occurs in the Voronka and Mezen Bay as a result of pressure and wind forces action in the Barents Sea. Then this disturbance penetrates through the Gorlo into the main part of the sea, causing a less significant increase of RSL in the entire water area. At the same time the highest values of RSL rise occur in the heads of the Dvina
and Onega Bays.
