Abstract: Based on the model of ideal frontogenesis in two dimensions, two kinds of finite difference scheme is tested. One scheme is a total energy conservation scheme that is used widely in atmosphere simulation, and the other one is an artificial compression method (ACM) that is used to capture the contact discontinuity in high-speed flows. Both of them have great abilities to simulate frontogenesis. But the effect of the ACM is better than the other to some extent.

Key words: frontogenesis, numerical simulation, ACM, conservation scheme
