Weather Forecast by Means of Filtered Equations in an Area Defined by Artificial Boundaries,
Abstract
In order to keep as small as possible the inevitable boundary errors in numerical forecasting within arbitrarily limited areas, it is suggested to use time dependent boundary values which originate from a simultaneously integrated outer much more coarse model. In principle, 'grid telescoping' is applicable to a quasi geostrophic model. To this end the well known prognostic model by Buleev and Marcuk is established for a horizontally limited area. On such a basis a specialized equivalent barotropic model as an outer model could furnish approximated boundary values for the inner model. (Author)
