Numerical treatment of cross-shelf open boundaries in a barotropic coastal ocean model.

Abstract

Using a barotropic coastal ocean model with a straight coastline and uniform cross shelf bottom slope, seven different cross shelf open boundary conditions (four of which are applied in either implicit or explicit form) are compared in three numerical experiments. (1) A mound of water is allowed to collapse and radiate waves toward the open boundaries. (2) A uniform alongshelf wind stress is applied at zero time over the entire shelf and held constant for the duration of the experiment. (3) A uniform cross shelf wind stress is applied at zero time over the entire shelf and held constant for the duration of the experiment. (from author's abstract)
