Numerical simulation of the generation of gravity waves in a frontal zone

Abstract

The generation of gravity waves in a frontal zone is investigated with a numerical model. The solutions show that gravity waves can be generated in a frontal zone by the application of a heating function which varies sinusoidaly with time, and that such waves propagate both ahead of and behind the frontal zone. The amplitude of the waves are directly proportional to the magnitude of the forcing function and to the period of sinusoidal oscillation. Even with large heating rates, no hydraulic jumps are formed.
