A modified atmospheric non-hydrostatic model on low aspect ratio grids

It is popular to use a horizontal explicit and a vertical implicit (HE-VI) scheme in the compressible non-hydrostatic (NH) model. However, when the aspect ratio becomes small, a small time-interval is required in HE-VI, because the Courant-Fredrich-Lewy (CFL) criterion is determined by the horizonta...
