Short summary
The non-hydrostatic compressible Euler equations were solved in a two-dimensional slice framework employing a spectral element method for the horizontal discretization and a finite difference method for the vertical. The results from the tests demonstrate that the horizontally spectral element vertically finite difference model is accurate and robust provided sufficient diffusion is applied. The combined spatial discretization method offers a viable method for development of a NH dynamical core.
