Simple algorithms to compute meridional overturning and barotropic streamfunction on unstructured meshes
Computation of barotropic and meridional overturning streamfunctions for models formulated on unstructured meshes is commonly preceded by interpolation to a regular mesh. This operation destroys the original conservation which can be then artificially imposed to make the computation possible. An ele...
