Abstract

The model has two interacting components, the coarse and fine grid regions. Nested calculations with 3:1 grid ratios are presented. Modeling of frontal features using nested models is addressed and topography is introduced, but without refinement of the grid in the vertical in the fine grid region. It is shown that the generation of noise at the interface of the fine grid and coarse grid regions in the presence of topography can be dealt with by the use of a Newtonian damping scheme. Comparison of the results of the nested model with a fine grid everywhere reference calculation shows the nesting technique to be working successfully over reasonably short periods of time integration (16 days). -from Authors
