I've reconciled that site, all looks good comparing to NOAA. The guy is a genius and is followed by quite a few U.S Met hot shots now. You need to go through all the menu's several times to digest the content (SAM is in there as well). The 3D image is a structure view, not the above view that earthnullschool displays of the vortex seperation.
Over the polar region the positive temperature anomalies become effective after the start of the low stratospheric vortex disturbance in June. As a consequence, the tropopause is continuously lowered and has propagated an enormous shift in the surface temps of Antarctica.
