Arakawa

Arakawa staggered grid arakawa grid
Staggered grid wrapping a base curvilinear grid — A / B / C / D / E variants — with per-stagger variable locations.
divergence_arakawa_c finite_volume arakawa scheme O(h²)
Two-point centered finite-volume divergence on a C-grid — F_x at face_x, F_y at face_y, divergence emitted at cell_center.
staggered_1st_uniform_cc_to_face finite_difference arakawa scheme O(h^2) (two-point centered difference at the half-offset face)
Auto-generated catalog entry for the staggered_1st_uniform_cc_to_face rule (finite_difference, grid family arakawa). The discrete operator is pretty-printed directly from the rule's replacement AST.
staggered_1st_uniform_face_to_cc finite_difference arakawa scheme O(h^2) (two-point centered difference at the half-offset cell center)
Auto-generated catalog entry for the staggered_1st_uniform_face_to_cc rule (finite_difference, grid family arakawa). The discrete operator is pretty-printed directly from the rule's replacement AST.
