Abstract
    The research carried out concerns the development of a numerical model for hydrodynamics (surface current and water elevation) and thermodynamics (surface temperature) of the Weddell Sea region. The knowledge of currents is necessary to predict the evolution of icefields, which is important for shipping and off-shore works in polar waters. A 2D numerical model has been used to simulate the currents in the Weddell Sea. The model uses a falsified alternating direction implicit (FADI) scheme. The numerical scheme gives rise to a very efficient computer implementation. The model has been verified by comparing the results of the model for some test cases with known solution. Attention was paid on the development of an appropriate open boundary condition and on the implementation of the advection -diffusion equation. The boundaries of the Weddell Sea model are situated at 50°S, 80°S, 80°W and 30°E, including the Antarctic Peninsula, the Drake passage and the southern tip of South America. The model has been used to calculate the wind induced and the tidal induced flows.
