I suppose a tornado could occur anywhere, but tornadoes are "driven" by
the heat of condensation of moist air due to an unstable inversion. Given
the lack of moisture in the Antarctic -- it is the largest desert on earth I
doubt that tornados are part of their weather pattern.

Dear Sir/Madame-
A tornado in Antarctica would be extremely rare. Tornadoes develop from
severe thunderstorms, and any kind of thunderstorm in that region is rare,
although they have been observed in the northernmost parts of the continent
and along the islands.

I do not know of any tornados having been reported in Antarctica.
However, theoretically, thunderstorms are a rare possibility
around the exterior and snow devils are possible in the interior.
