I apologize if this has been suggested before, but I believe the "Distances in the South" wiki article has a typo.
https://wiki.tfes.org/Distances_in_the_SouthIt reads "[The FE] proposed models predict that the lines of latitude south of the equator will either converge or diverge." But it's the lines of
longitude (the ones going north/south) that diverge (in monopole maps) and converge (in bi-polar FE maps).
I think it's just a matter of a simple typo.
