WHOLE ATMOSPHERE MODELING: CONNECTING TERRESTRIAL AND SPACE WEATHER (2011, background): “At the same time both grid point and spectral models rely on artificial numerical horizontal diffusion preventing from accumulation of power at smallest resolved scales, which may result in numerical instability [e.g., Davies et al., 2005; Hamilton et al., 2008; Satoh et al., 2008].”
