two things.
I live in new zealand, and work as a meteorologist, i observe weather patterns coming from our south, over antarctica. that's south, not east. i also don't remember crossing over antarctica when i flew to south america, in fact we stopped in samoa, and with the distance between land masses in that map, we would have been traveling at twice the speed of sound.
furthermore, antarcrica is also due south of africa, the nation of south africa has sent meteorologists to Scott Base in antarctica, many times in the past. they flew straight south to get there... not from one edge of the earth-disc to the other.
