 Through the introduction of a reference atmosphere, prognostic variables become smoother on the tilted sigma-surface over mountains or a frontal zone, and thus truncation errors are reduced. Truncation errors of selected finite difference methods for two-dimensional advection-diffusion equation with mixed derivatives This paper presents the calculation of truncation errors, namely numerical diffusion and numerical dispersion for various finite difference schemes. The effect of truncation errors is considered in the incremental virtual work equation.
