Prognostic variables can be positioned at different places on a computational grid leading to staggered or unstaggered grids. The Charney--Phillips vertical staggering has the correct degrees of freedom so as to avoid the computational mode that is associated with the Lorenz vertical staggering.

We present a 2D vertical slice test case based on the test case by Arakawa & Konor 1996 that excited the Lorenz computational mode. We also experiment with the Schär mountain waves test case to excite the computational mode over orography.
