白令海峡及其邻近海域潮汐潮能数值模拟
NUMERICAL STUDY OF THE BAROTROPIC TIDE AND TIDAL ENERGY DISTRIBUTION IN THE BERING STRAIT AND ADJACENT SEA AREAS
摘要
Abstract
Based on the Finite-Volume Coastal Ocean Numerical Model(FVCOM), a high-resolution hydrodynamic model was es-tablished to study the tides and tidal energetics in the Bering Strait and its adjacent sea areas. The model results were found in good agreement with tide gauge and current data, and the model simulated the hydrodynamics well. Co-tidal charts and the tidal current ellipses of the major constituents were drawn and they were discussed using the calculated results. It was shown that the M2 constituent is dominant in the Bering Sea Shelf, Bering Sea, and Chukchi Sea, whereas the K1 constituent is dominant in Norton Sound. The M2 constituent tidal current velocity is larger in the area of the southeast Bering Sea shelf and Anadyr Bay. The maximum tidal current velocity of the K1 constituent appears in Norton Sound. The model output indicated that the tidal energy flux is small and that the total energy dissipation of the major constituents in the research area is about 751 MW; the M2 tidal energy dissipation accounts for 52% and the K1 tidal energy dissipation accounts for 38%. When the tide enters the Bering Sea shelf, most of the M2 constituent energy is dissipated to the south of St. Lawrence Island, while most of the K1 constituent energy is dissipated in Norton Sound.关键词
