+Figure 4: Sketch of the topography implementation using the mask method (here for ''w''). The yellow line represent the region where the prognostic terms for scalars and the ''w''-component are masked, while the red line indicates the region where special surface-bounded code is masked.
+Additional surface-bounded code is executed at grid points in between the yellow and the red line (see [wiki:doc/tec/topography topography implementation]).
