22.12 diago

After the external mode has been solved, the remaining diagnostics can be calculated and written out. This is done in subroutine diago^22.29 and described in Chapter 38.

**Figure 22.2:** The horizontal grid layout within a memory window of size *jmw*=3 indicating cells, grid points, and sites where derived quantities can be defined. Allowable sited determine how arrays must be dimensioned within the memory window.

**Figure 22.4:** a) Column of ocean T-cells in relation to bottom topography. ``x'' denotes vertical velocity at the base of ocean bottom T-cells. ``black dot'' denotes vertical velocity at the base of an ocean bottom U-cell. ``open circle'' denotes position of bottom vertical velocity from continuous equation. b) Corresponding column of ocean U-cells. c) Truncated ocean U-cells below bottom of the U-cell column.
