Arakawa grids Arakawa grids The Arakawa grid system depicts different ways to represent and compute orthogonal physical quantities (especially velocity- and mass-related quantities) on rectangular grids used for Earth system models for meteorology and oceanography. For example, the Weather Research and Forecasting Model uses the Arakawa Staggered C-Grid in its atmospheric calculations when using the ARW core. The five Arakawa grids (A-E) were first introduced in Arakawa and Lamb 1977. For an image of the five grids, see the following picture, or Fig. 1 in Purser and Leslie 1988. The "unstaggered" Arakawa A-grid evaluates all quantities at the same point on each
