review text: The paper deals with the barotropic numerical shelf sea model (IAP model) of the Institute of Atmospheric Physics, Chinese Academy of Sciences. The effects of wind stress on the sea-surface elevation and the current region over a shelf sea area are investigated. Authors point out that, in contrast to other models of this kind, the IAP model has two unique features: \((a)\) variable substitution is introduced into the governing equations, which puts the energy equation into a compact form; \((b)\) the difference scheme designed preserves the properties of mass and energy conservation of original coastal flows involving open sea boundaries. For computing economy, a splitting is adoped in the IAP model, dividing the governing equations into three stages: adjustment, development, and forcing-dissipation. Application of the splitting method requires open boundary conditions (OBCs) to be also split correspondingly. The proposed OBCs are validated by two test cases: \((a)\) an experiment with a fluid contained within an infinitely long channel, where the OBCs are applied at two cross sections along it; \((b)\) the steady response of an open sea to stationary cyclone.
